Self-Hosted Video Conferencing: 9 Best Platforms

Self-hosted video conferencing allows organizations to run video meetings on infrastructure they control instead of relying entirely on a third-party conferencing provider. Companies can deploy conferencing software in their own data centers, private clouds, or customer-managed hosting environments to control server access, network connectivity, user authentication, and the storage of meeting-related information.

The main benefits are infrastructure control, data sovereignty, customization, integration with existing IT systems, and the ability to communicate within private networks. Self-hosted video conferencing is particularly relevant to enterprises, government agencies, healthcare institutions, universities, and businesses with strict security or operational requirements. However, it also introduces responsibility for server maintenance, capacity planning, security updates, and service availability.

Popular self-hosted video conferencing solutions include Jitsi Meet, Nextcloud Talk, OpenTalk, BigBlueButton, OpenVidu Meet, Pexip Infinity, TrueConf Server, LiveKit, and MiroTalk. These products serve different purposes: some provide complete meeting environments, others specialize in education or corporate communications, while developer-oriented platforms offer the infrastructure required to build custom video applications.

Self-Hosted Video Conferencing at a Glance

The main difference between self-hosted and cloud video conferencing is who operates the conferencing environment. Public cloud services normally provide ready-made meeting applications with vendor-managed infrastructure. Self-hosted systems give organizations control over how conferencing servers are configured, maintained, and integrated with their existing networks.

That control is valuable when communication must follow internal IT policies, use existing authentication systems, or remain available in restricted networks. It does not automatically guarantee lower costs or stronger security. The outcome depends on the product, its dependencies, the deployment architecture, and the organization's technical capabilities.

What Is Self-Hosted Video Conferencing?

Self-hosted video conferencing is a communication model in which an organization deploys and operates video meeting software on infrastructure under its administrative control.

The software typically handles meeting creation, participant authentication, audio and video communication, screen sharing, and optional services such as recording or streaming. Users connect through desktop applications, mobile clients, browsers, or compatible conference room equipment.

Unlike conventional Software as a Service platforms, self-hosted systems allow organizations to manage the application environment, determine where communication services operate, and establish their own network and storage policies.

Self-hosting does not necessarily require physical servers inside a company's office. A conferencing application installed on customer-managed cloud instances may also qualify as self-hosted. The defining factor is who controls and operates the application.

How Does Self-Hosted Video Conferencing Work?

A typical self-hosted conferencing platform includes signaling services, media infrastructure, authentication, and client applications.

When a participant joins a meeting, the application establishes a session through the conferencing environment. Signaling services coordinate connections, while media components transmit or process audio and video according to the platform's architecture.

Some systems forward media streams between participants. Others decode and combine streams before transmitting them to receiving devices. Peer-to-peer applications may establish direct connections when network conditions permit.

Recording, transcription, streaming, monitoring, and directory integration can require additional services. Consequently, installing the conferencing interface is only one part of preparing a production environment.

A basic Jitsi Meet deployment, for example, differs considerably from an enterprise installation of Pexip Infinity or TrueConf Server, although all three can operate on privately managed infrastructure.

Self-Hosted vs. On-Premises vs. Private Cloud

These terms describe related but different aspects of deployment.

An on-premises conferencing system is generally self-hosted, but a self-hosted system does not have to be on-premises.

A dedicated vendor-managed instance is not necessarily equivalent to customer-operated software. Businesses should establish who controls administrative access, upgrades, backups, encryption keys, and the underlying operating environment before selecting a deployment model.

Why Do Organizations Choose Self-Hosted Video Conferencing?

The primary reason is the ability to align communication infrastructure with internal technical, security, and operational requirements.

Data Sovereignty and Infrastructure Control

Self-hosting allows organizations to determine where conferencing servers and associated storage systems operate.

This can be important for businesses that need meeting recordings, employee information, and communication services to remain within a particular jurisdiction or approved infrastructure environment. The company can select the data center, establish storage policies, and define who is authorized to administer the system.

Data sovereignty, however, depends on more than server location. Backups, telemetry, support access, external authentication, and third-party integrations must also be considered.

Communication Within Private Networks

Some organizations restrict access to public communication services because of security policies or operational requirements.

A suitable self-hosted conferencing platform can support meetings across a corporate LAN, private WAN, or VPN. In supported configurations, the system may also operate without public internet connectivity.

This is relevant to industrial facilities, research institutions, government agencies, and companies operating restricted networks. Whether a particular product can operate autonomously must be verified through its licensing and technical documentation.

Integration With Existing IT Infrastructure

Businesses may need conferencing software to work with corporate directories, authentication providers, monitoring systems, firewalls, and existing conference room equipment.

Platforms supporting LDAP, Active Directory, SSO, SIP, or H.323 can simplify integration with established infrastructure. For example, an enterprise may want employees to use their existing accounts while connecting professional conference room terminals to the new system.

These capabilities vary between products and licensing editions, so compatibility should be tested for the intended deployment.

Customization and Application Development

Open-source solutions and developer-oriented conferencing platforms allow organizations to create custom interfaces, automate meeting workflows, and integrate live communication into their own applications.

A software company may embed customer consultations into its portal, while an enterprise might connect video meetings with internal scheduling or technical support systems.

The degree of customization depends on the product. A programmable media framework offers extensive development freedom, while a ready-to-use enterprise suite may provide a more complete interface and supported administration tools.

Greater Control Over Operating Costs

Self-hosting changes how conferencing expenses are allocated. Instead of paying only recurring subscriptions, an organization may invest in server resources, software licenses, maintenance, and internal administration.

For companies with existing infrastructure and predictable concurrency, this model can be economical. For smaller teams without technical resources, the additional operational workload may outweigh the benefits.

The financial decision should be based on total cost of ownership rather than the initial software price.

Self-Hosted Video Conferencing Statistics and Infrastructure Trends in 2026

Reliable public statistics specifically measuring global adoption of self-hosted video conferencing platforms are limited. Most enterprise technology surveys track broader categories such as cloud computing, collaboration applications, and communication services. Consequently, general cloud adoption figures should not be interpreted as direct evidence of how many organizations operate private conferencing servers.

According to Eurostat's February 2026 publication, 52.7% of EU enterprises purchased cloud computing services in 2025, compared with 45.3% in 2023 and 17.8% in 2014. The survey covered enterprises with at least ten employees or self-employed persons in specified economic activities.

What These Statistics Mean for Self-Hosted Conferencing?

The figures do not demonstrate whether the use of self-hosted video conferencing is increasing or decreasing. They show that businesses operate in environments where vendor-managed cloud services, privately managed applications, and internal infrastructure can coexist.

A company may use SaaS for routine meetings while operating a separate conferencing system for sensitive communication. Another organization may deploy its own conferencing application on rented cloud servers. The relevant decision is therefore not simply whether to use cloud infrastructure, but which conferencing workloads require direct administrative control.

Insight 1: Self-Hosting Is an Operating Model, Not a Physical Location
A conferencing system does not become less self-hosted because it runs in a rented data center.
The more useful questions concern control. Who manages the application? Who can access server configuration? Where are recordings stored? Who controls upgrades? Which external services are necessary for normal operation?
A customer-managed cloud instance may provide substantial operational control. Conversely, a server physically located in an office but completely administered by an external provider may provide less direct control.
Infrastructure ownership, application administration, data sovereignty, and service availability should be evaluated as separate requirements.

Best Self-Hosted Video Conferencing Platforms

There is no universal best self-hosted video conferencing platform because the products address different communication scenarios.

Some provide complete employee-facing meeting environments. Others integrate conferencing with corporate messaging and file management. Developer-oriented solutions provide media infrastructure and APIs but may require organizations to build their own user interfaces.

The following nine platforms offer documented self-hosted deployment options.

Self-Hosted Video Conferencing Software Comparison

1. Jitsi Meet

Best for: Organizations looking for open-source conferencing with browser access, customizable functionality, and self-managed infrastructure.

Jitsi Meet is an open-source video conferencing application built around WebRTC technologies. It supports meetings through compatible browsers and mobile applications, making it accessible to employees and external participants without specialized conferencing equipment.

Its primary strength is combining a ready-made meeting interface with flexible server deployment and customization.

Jitsi Videobridge and SFU Architecture

One of Jitsi's distinguishing components is Jitsi Videobridge, which uses a Selective Forwarding Unit architecture.

Instead of combining all participants into a single video stream, the bridge forwards selected media streams between participants. This generally reduces server-side processing compared with full media mixing, although bandwidth consumption and participant device performance remain important.

A production deployment also requires signaling and conference coordination components, which administrators must configure as part of the complete system.

Browser Meetings and Collaboration

Jitsi Meet supports audio and video meetings, screen sharing, chat, and participant controls. Recording, streaming, and additional services can be configured through appropriate components.

For example, a development company may use Jitsi for technical discussions, allowing employees to demonstrate application changes while the IT department manages the conferencing environment. Browser access can also make it easier to invite contractors who do not use the same corporate desktop software.

Authentication and Customization

Organizations can configure authentication requirements and meeting access policies. A company may restrict meeting creation to authenticated employees while permitting authorized external guests to join existing conferences.

Jitsi also provides development tools for integrating the conferencing interface into other applications. These capabilities are relevant to IT teams that want to manage meeting access through existing systems rather than rely on a public meeting portal.

Encryption

Jitsi encrypts media traffic in transit and supports optional end-to-end encryption in compatible client configurations. However, the optional protection does not automatically apply to every collaboration feature, including text chat and polls.

Security reviews should distinguish transport encryption from optional end-to-end media protection and consider how individual meeting features are implemented.

Infrastructure and Administration

Jitsi's official self-hosting handbook provides installation and configuration instructions but does not establish one universal server size that guarantees a particular number of participants.

Capacity depends on the number of media bridges, concurrency, recording services, network throughput, and participant workloads. Organizations should begin with a representative deployment, monitor media traffic, and increase resources according to measured usage rather than rely solely on registered user counts.

Business benefit: Jitsi Meet provides a customizable conferencing environment for organizations seeking open-source software and control over deployment.

Strengths: Open-source software, browser participation, Jitsi Videobridge, screen sharing, customization, and flexible self-hosting.

Limitations: Large deployments require technical expertise. Recording, enterprise authentication, and production-scale availability may involve additional infrastructure.

2. Nextcloud Talk

Best for: Organizations that want video conferencing and messaging connected to privately managed documents.

Nextcloud Talk is a communication application integrated with the Nextcloud collaboration environment.

It connects conversations and video meetings with files stored in an organization's Nextcloud infrastructure. This can simplify communication for businesses that already use Nextcloud for document management.

Messaging and Video Meetings

Nextcloud Talk provides direct and group conversations, audio and video calls, screen sharing, and meeting controls.

Employees can discuss a project through persistent messages, organize a meeting, and continue the conversation afterward. Depending on the deployed version and supporting components, additional capabilities may include polls, breakout rooms, recording, and collaboration integrations.

The value of this approach is continuity between everyday discussions and scheduled meetings.

Integration With Nextcloud Files

Nextcloud Talk connects communication with documents stored in Nextcloud.

For example, a legal team can maintain contract drafts within an approved workspace and discuss revisions during a call without distributing uncontrolled copies through external messaging applications.

Access to the underlying files remains governed by Nextcloud permissions. This makes Talk particularly useful when a company wants communication to remain connected to an existing document environment.

High Performance Backend

Larger Nextcloud Talk deployments can use a High Performance Backend that provides additional signaling and media infrastructure.

Its SFU functionality forwards media between participants, making the architecture better suited to substantial conferencing workloads than a minimal installation. Administrators should assess expected concurrency and the performance requirements of these additional components when planning infrastructure.

Federation

Nextcloud Talk supports federated communication between compatible Nextcloud installations, enabling selected users from different organizations to communicate without maintaining all accounts on one central server.

Such connections require appropriate network accessibility, access permissions, and administrative policies. They are particularly relevant when organizations collaborate but want to maintain separate account and server environments.

Practical Application

A professional services company already uses Nextcloud for file storage and collaborative documents. By deploying Talk, the IT department adds video meetings and persistent conversations to the same environment.

Employees can review project materials, discuss changes live, and continue working with the authorized files afterward.

Business benefit: Nextcloud Talk combines video conferencing, messaging, and document collaboration in a self-managed workspace.

Strengths: Nextcloud Files integration, persistent messaging, video calls, screen sharing, federation, and optional high-performance infrastructure.

Limitations: Larger deployments require additional backend resources. The platform is most valuable when an organization also uses Nextcloud's broader collaboration environment.

3. OpenTalk

Best for: Enterprises and public institutions conducting structured meetings with moderation, voting, and corporate identity integration.

OpenTalk is a conferencing platform available through hosted services and on-premises enterprise deployment.

It emphasizes moderated meetings, structured participation, and integration with organizational infrastructure. This makes it suitable for formal discussions that require more control than an ordinary group video call.

Structured Meetings and Moderation

OpenTalk provides meeting scheduling, waiting rooms, participant controls, and moderation features.

Organizers can manage access and coordinate discussions according to the meeting's purpose. This is relevant to committees, associations, and public institutions where participant roles and meeting procedures need to be clearly defined.

The platform is designed to support organized meetings rather than simply connect cameras and microphones.

Polls and Breakout Rooms

OpenTalk supports polling and selected voting functionality, as well as breakout rooms for smaller discussions.

A public institution can use these tools to review proposals, gather participant responses, and divide a larger meeting into working groups. Specific capabilities depend on the edition and licensing, so organizations conducting formal voting should verify that the available functions meet their procedural requirements.

Whiteboards and Presentations

OpenTalk provides screen sharing and collaborative whiteboards. Participants can review documents, annotate visual materials, and discuss proposed changes.

These tools help teams work through complex proposals without requiring everyone to be physically present.

Enterprise Deployment and Identity Integration

OpenTalk Enterprise can be deployed in an organization's own data center. According to its official documentation, the enterprise product uses Docker container technology and supports distributing components across multiple systems for high availability and horizontal scaling.

OpenTalk integrates with Keycloak, allowing organizations to connect compatible identity sources, including LDAP and Microsoft Active Directory. Single Sign-On and two-factor authentication can be implemented through suitable identity configurations. The enterprise offering also supports multiple tenants, providing separate environments for different organizational units or customers.

The provider's deployment documentation has described Kubernetes support as under development. Organizations should verify the support status for the version they intend to install rather than assume that a Kubernetes deployment is covered by standard production support.

Practical Application

A public institution deploys OpenTalk Enterprise on approved infrastructure and connects authentication to its employee directory.

Meeting organizers manage attendance, conduct polls, and organize smaller discussions while maintaining the institution's established access policies.

Business benefit: OpenTalk combines structured meeting participation with enterprise identity integration and privately operated infrastructure.

Strengths: Moderation, polls, breakout rooms, corporate authentication, Docker-based deployment, and multitenancy.

Limitations: Enterprise deployment requires commercial licensing and administration. Advanced capabilities and supported orchestration methods must be verified for the selected edition.

4. BigBlueButton

Best for: Schools, universities, training providers, and organizations operating interactive virtual classrooms.

BigBlueButton is an open-source conferencing platform designed primarily for teaching and learning.

Unlike general-purpose meeting software, it provides tools organized around instructor-led lessons, participant engagement, and collaborative exercises.

As of November 2026, BigBlueButton 4.0 is the latest released major version, with version 4.0.1 published on October 29, 2026. Version 4.1 is documented as in development rather than as a released stable edition. The official release history provides the appropriate reference for checking the version status.

Virtual Classrooms and Whiteboards

BigBlueButton combines audio and video communication with presentations, screen sharing, and a multi-user whiteboard.

Instructors can annotate materials and invite students to interact with diagrams or presentations. For example, a technical trainer can display a network diagram and ask participants to identify components or suggest improvements.

The whiteboard creates a shared workspace for instruction rather than limiting participants to passive viewing.

Breakout Rooms, Polls, and Quizzes

BigBlueButton supports breakout rooms, allowing instructors to divide participants into smaller working groups.

Polls and shared notes help teachers assess understanding and collect feedback. Quizzes also provide a way to ask questions with defined answers and review participant responses.

In a professional training session, participants can examine a scenario in groups, present their findings, and complete a short quiz to check understanding.

These features make BigBlueButton more suitable for structured learning than a platform designed exclusively for ordinary business meetings.

Learning Analytics Dashboard

BigBlueButton includes a Learning Analytics Dashboard with information about attendance and participation indicators.

Supported releases provide additional visibility into activity within breakout rooms. Instructors can use these indicators to identify students who may benefit from additional guidance.

However, activity metrics should support instructional decisions rather than be treated as definitive measures of learning outcomes. A participant who speaks frequently is not necessarily learning more than someone who contributes through written answers or assignments.

Recording and LMS Integration

BigBlueButton provides recording and playback functionality, allowing students to revisit lessons or review materials after a session.

The platform can integrate with learning management systems through supported APIs and connectors. A university, for example, can connect virtual classrooms to Moodle and manage access through its existing course environment.

BigBlueButton 4.0 introduces significant changes to its conferencing infrastructure and client interface, including expanded use of LiveKit for real-time media. Organizations operating custom integrations or plugins should test compatibility with the released 4.0 series before migrating production workloads.

BigBlueButton 4.0 Server Requirements

The official BigBlueButton 4.0 installation guide recommends a clean, dedicated Ubuntu 24.04 server for production.

The published minimum recommendations include eight CPU cores with strong single-thread performance, 16 GB RAM with swap enabled, and at least 250 Mbps symmetrical network connectivity.

Recording-enabled deployments require substantially more storage than systems operating without recordings. The installation guide specifies 500 GB or more of free disk space when recordings are enabled and 50 GB when recording is disabled.

These requirements are version-specific and should not be applied to other conferencing applications.

Migrating From BigBlueButton 3.0 to 4.0

BigBlueButton 3.0 uses Ubuntu 22.04, while version 4.0 requires Ubuntu 24.04.

The official documentation states that a direct in-place upgrade from BigBlueButton 3.0 to 4.0 is not supported. Instead, administrators should prepare a clean Ubuntu 24.04 installation, deploy BigBlueButton 4.0, and migrate existing recordings.

The migration should also include testing of LMS connectors, authentication, custom plugins, recording access, and meeting workflows.

For a university running many simultaneous classes, this is an operational planning issue rather than a simple software update. Administrators should test the new environment before transferring production meetings.

Business benefit: BigBlueButton provides a purpose-built virtual classroom with interactive teaching tools, recordings, and learning analytics.

Strengths: Open-source licensing, whiteboards, breakout rooms, polls, quizzes, recordings, education-focused analytics, and LMS integration.

Limitations: The platform is primarily designed for education. Production deployment requires dedicated infrastructure, and migration from 3.0 to 4.0 requires a new server installation.

5. OpenVidu Meet

Best for: Developers and software vendors requiring embeddable video conferencing with APIs and self-managed deployment.

OpenVidu Meet is an open-source conferencing application designed for self-hosting and integration into other software.

It combines a ready-made meeting interface with developer-oriented APIs and customizable workflows, making it useful for companies adding video communication to their own services.

Browser Meetings and Collaboration

OpenVidu Meet provides video and audio communication, screen sharing, chat, and meeting controls.

Supported configurations also offer collaboration functions such as whiteboards, notes, and breakout rooms. These capabilities allow developers to integrate a complete meeting experience without building every interface component themselves.

APIs, Webhooks, and Embedding

OpenVidu Meet provides REST APIs, webhooks, and embedding options.

Developers can connect meeting creation, participant permissions, and conference events to existing applications. For example, a customer support platform can create video consultation rooms directly from customer records and control access through its own workflow.

Meeting Permissions and Recording

OpenVidu Meet supports configurable meeting roles and recording options. Recordings can be enabled for appropriate rooms, with manual or automatic triggers depending on configuration.

These capabilities can support applications where customer interactions must be documented or reviewed.

End-to-End Encryption

OpenVidu Meet supports end-to-end encryption for audio, video, chat messages, and participant names in compatible configurations.

Its official documentation states that end-to-end encryption and server-side recording cannot be enabled simultaneously for the same room.

This illustrates how encryption requirements can affect the availability of other meeting functions. Organizations that require protected content and recorded sessions should evaluate the trade-off before designing their application workflows.

Practical Application

A software company adds video consultations to its customer portal.

OpenVidu Meet supplies the conferencing application, while APIs and webhooks connect meetings with scheduling, authentication, and customer records. The company operates the conferencing environment on infrastructure it manages.

Business benefit: OpenVidu Meet enables companies to integrate self-hosted video communication into applications without developing every conferencing function from scratch.

Strengths: Embedding, REST APIs, webhooks, meeting permissions, recording, and optional E2EE.

Limitations: Deployment and integration require technical expertise. E2EE is incompatible with server-side recording in the documented room configuration.

6. Pexip Infinity

Best for: Enterprises requiring professional conferencing, distributed infrastructure, and integration with existing video equipment.

Pexip Infinity is a self-hosted conferencing platform designed for enterprise video communication and interoperability.

Its principal advantage is the ability to operate a distributed conferencing environment that connects different types of compatible endpoints.

Distributed Conferencing Infrastructure

Pexip Infinity supports deployment across data centers, private clouds, supported public cloud environments, and hybrid configurations.

Organizations can distribute conferencing nodes according to geographical locations and network requirements. This is useful for enterprises with multiple offices or regional IT infrastructure, particularly when conferencing services need to operate near groups of users.

SIP and H.323 Interoperability

Pexip supports compatible SIP and H.323 video conferencing terminals.

This allows businesses to connect professional room systems with virtual meeting environments and compatible browser participants. For example, a company using Cisco or Poly equipment can evaluate Pexip without immediately replacing every endpoint.

Compatibility still depends on equipment models, software versions, codecs, and configuration.

WebRTC and Browser Participation

Pexip supports browser-based conferencing through compatible WebRTC environments.

Remote employees and guests can join supported conferences even when other participants use professional room systems. This is valuable for organizations with established hardware investments and distributed teams.

Administration and Protocol Management

Pexip provides conference management, diagnostics, and controls for supported communication protocols.

Administrators can configure protocol availability and monitor relevant system activity. The platform also provides APIs and customization options for enterprise integration.

These capabilities help IT teams align conferencing services with existing network and administrative policies.

Practical Application

A multinational company wants to operate private conferencing infrastructure while preserving meeting room equipment across regional offices.

Pexip Infinity can provide a distributed conferencing environment that connects compatible terminals and browser participants. The organization manages its conferencing infrastructure without requiring every location to replace existing devices.

Business benefit: Pexip Infinity helps organizations maintain conferencing investments while supporting privately managed enterprise communication.

Strengths: Distributed infrastructure, SIP/H.323 compatibility, browser participation, protocol management, and enterprise administration.

Limitations: Licensing and deployment can be complex. The platform may be excessive for businesses requiring only basic online meetings.

7. TrueConf Server

Best for: Enterprises, public sector organizations, and industrial companies requiring private conferencing and corporate messaging.

TrueConf Server is an on-premises communication platform combining video conferencing, persistent messaging, and collaboration tools.

It provides an employee-facing communication environment that organizations can operate on their own infrastructure. Unlike developer-oriented media frameworks, TrueConf Server includes dedicated clients, corporate directories, persistent conversations, and multiple conferencing modes.

Conference Modes and Participant Management

TrueConf Server supports personal calls, group conferences, and larger events. Depending on licensing, a single conference can accommodate up to 2,000 participants.

Organizers can manage participant access, video layouts, speaking permissions, and conference formats, allowing companies to arrange routine coordination meetings, training sessions, management discussions, and large presentations.

Video Quality and Collaboration

TrueConf supports high-resolution video, including Ultra HD capabilities in suitable configurations.

Actual quality depends on the network, endpoint hardware, conference settings, and licensing. The platform also provides screen sharing, presentations, annotations, and supported remote desktop control.

An engineer can, for example, assist an employee at a remote facility by reviewing an application through screen sharing and, where authorized, using remote control.

Corporate Messaging and Channels

TrueConf Server provides persistent direct chats, group conversations, channels, and file exchange. Employees can discuss problems, coordinate projects, and exchange documents without opening a separate meeting every time information needs to be shared.

When a live explanation becomes necessary, employees can move from messaging to a video conference within the same communication environment.

Active Directory and LDAP

TrueConf Server supports Active Directory and LDAP integration, allowing organizations to connect the platform to existing user directories and simplify account administration.

This is relevant to enterprises with centralized identity management, established corporate contact lists, and formal employee access policies.

SIP and H.323 Interoperability

TrueConf Server supports compatible SIP and H.323 video conferencing equipment.

Businesses can evaluate the integration of supported professional room systems instead of replacing every endpoint when adopting the platform.

Browser-based participation is also available for supported guest scenarios, subject to server accessibility and meeting configuration.

Autonomous Operation in Private Networks

TrueConf Server can run on Windows or Linux infrastructure controlled by the organization.

Its full licensed edition supports autonomous internal communication in suitable private or isolated networks without requiring public internet access for normal operation.

This is relevant to manufacturing facilities, research centers, government environments, and other organizations with restricted connectivity.

The free edition has different registration and connectivity requirements. Organizations planning offline deployment should verify the selected license before implementation.

Recordings and AI Functions

TrueConf supports recording in appropriate conferencing configurations.

Additional products, including TrueConf AI Server, can provide transcription and summarization. These functions depend on the selected software, infrastructure, integration components, and licensing.

Practical Application

A manufacturing company operates several plants connected to headquarters through an internal network.

When a technical problem appears at a regional facility, an employee contacts the engineering department through corporate chat. The engineer starts a video conference, reviews the relevant application, and provides troubleshooting guidance.

The company can conduct this communication within its managed infrastructure without relying on a public cloud meeting service.

Business benefit: TrueConf Server combines corporate messaging, video conferencing, directory integration, and private infrastructure control.

Strengths: Integrated communication environment, enterprise conferencing, screen sharing, SIP/H.323 interoperability, directory integration, and support for isolated networks.

Limitations: Self-hosted operation requires infrastructure administration. Conference capacities and some advanced functions depend on licensing or additional products.

8. LiveKit

Best for: Developers building custom real-time audio, video, and communication applications.

LiveKit is a programmable media infrastructure platform that supports self-hosted deployment.

Unlike a ready-made enterprise conferencing application, LiveKit primarily provides the media services and SDKs developers need to build communication products.

SFU-Based Media Infrastructure

LiveKit uses an SFU architecture for real-time audio and video.

Participants send media to the server, which forwards selected streams to others. This allows developers to create multiparty communication systems without building their own media routing engine.

SDKs and Developer Integration

LiveKit provides APIs and SDKs for implementing audio and video applications.

A logistics company, for example, can add live communication to its internal operations dashboard. Employees start calls from operational records, while the company's software handles user interfaces, authentication, and related business workflows.

Recording and Media Ingestion

LiveKit supports recording and streaming through its Egress service, which must be deployed and operated as an additional component in self-hosted environments.

LiveKit also provides media ingestion capabilities through supported protocols such as RTMP, WHIP, and SRT. SIP integration is available through the relevant infrastructure components.

Encryption

LiveKit supports end-to-end encryption in compatible client configurations.

Infrastructure and Capacity

LiveKit's deployment documentation identifies CPU and network bandwidth as important scalability constraints.

For production media infrastructure, its guidance recommends high-capacity networking, including 10 Gbps Ethernet or faster for suitable production environments.

This is a recommendation for production-oriented deployments, not a universal minimum for every small self-hosted instance. The number of participants, subscribed streams, recording workloads, and deployment topology determine actual resource needs.

Business benefit: LiveKit provides programmable media infrastructure for companies that want to develop custom communication applications.

Strengths: Self-hosted SFU infrastructure, SDKs, recording services, media ingestion, SIP integration, and flexible application development.

Limitations: LiveKit is not a complete corporate meeting suite by default. Developers must implement the required interfaces, workflows, identity controls, and administrative functions.

9. MiroTalk

Best for: Smaller organizations and developers seeking self-hostable WebRTC conferencing applications.

MiroTalk is a family of communication products with different architectures for peer-to-peer calls, SFU conferencing, broadcasting, and meeting administration.

Organizations can choose the application that matches their intended communication model, but licensing and infrastructure requirements differ between products.

MiroTalk P2P

MiroTalk P2P supports direct media connections between participants when network conditions permit.

It can be useful for smaller meetings and custom video calling applications. TURN infrastructure may be required when direct communication is blocked by network restrictions.

Peer-to-peer conferencing generally becomes less practical as participant numbers increase because devices may need to maintain multiple media connections.

MiroTalk SFU

MiroTalk SFU uses a Selective Forwarding Unit to distribute media between participants.

Its documented functionality includes screen sharing, chat, whiteboards, recording, and integration options. This architecture is better suited to multiparty communication than a basic peer-to-peer mesh.

MiroTalk SFU supports deployment through Node.js or Docker in suitable environments.

MiroTalk BRO

MiroTalk BRO focuses on presenter-to-audience communication and supports broadcast-oriented configurations, including documented peer-to-peer and SFU distribution modes.

This can be useful for webinars and live events where a limited number of people transmit media to a larger audience.

MiroTalk WEB and APIs

MiroTalk WEB provides meeting scheduling and management capabilities for supported MiroTalk applications.

The individual conferencing applications remain separate products. MiroTalk also provides APIs, widgets, and embedding options for organizations integrating meetings into websites or business applications.

Licensing varies by product and intended use. The official SFU product documentation describes a one-time purchase model with different license types for distribution and monetization.

MiroTalk SFU Server Requirements

The official MiroTalk SFU product page specifies an entry-level configuration with Ubuntu 22.04 LTS, at least two vCPU, 4 GB RAM, and Node.js 22 or newer, or Docker.

The deployment also requires a domain, DNS configuration, TLS certificates, and suitable network connectivity.

These are baseline installation requirements, not a guarantee that the server will support a specific number of concurrent participants or high-resolution streams. Capacity depends on media quality, server resources, outbound bandwidth, and deployment design.

For developers planning group conferences, these requirements provide a useful starting point, but production capacity still needs to be measured.

Practical Application

A small software company needs individual video consultations within its customer portal.

It may evaluate MiroTalk P2P for small conversations and consider MiroTalk SFU if multiparty meetings become necessary.

The decision depends on expected concurrency, network topology, and available technical resources.

Business benefit: MiroTalk provides several self-hosted communication architectures that developers can select according to their requirements.

Strengths: P2P and SFU options, broadcasting, screen sharing, recording, embedding capabilities, and accessible entry-level deployment specifications.

Limitations: MiroTalk consists of separate products with different requirements and licensing conditions. Capacity depends on the chosen application and infrastructure.

Self-Hosted Video Conferencing Features Compared

Not every self-hosted product provides the same level of functionality.

Some deliver a complete meeting application, while others supply programmable media infrastructure for software developers.

Capabilities depend on the product version, licensing, installed components, and configuration.

Ready-to-Use Conferencing vs. Developer Infrastructure

Ready-to-use conferencing platforms provide meeting interfaces that employees can use after installation and configuration.

Jitsi Meet, Nextcloud Talk, OpenTalk, BigBlueButton, Pexip Infinity, and TrueConf Server belong broadly to this category, although their intended audiences differ.

Developer platforms focus on media services, APIs, and integration. LiveKit is a clear example: it provides real-time infrastructure, but organizations building a complete communication product must also develop or integrate interfaces, authentication, and business workflows.

OpenVidu Meet occupies a more integrated position because it combines a conferencing application with APIs and embedding capabilities.

The distinction matters because the cost of building and maintaining an application can exceed the cost of operating the media infrastructure itself.

Self-Hosted Video Conferencing Architecture: P2P vs. SFU vs. MCU

The conferencing architecture affects server processing, client bandwidth, network requirements, and scalability.

Three common approaches are peer-to-peer communication, Selective Forwarding Units, and Multipoint Control Units.

Peer-to-Peer Conferencing

In a peer-to-peer conference, participants exchange media directly when network conditions allow.

This reduces the need for centralized media processing, but each participant may need to send and receive multiple streams as the group grows.

P2P is generally more practical for small meetings than large interactive conferences.

Selective Forwarding Unit

An SFU receives media streams and forwards selected streams to participants.

It generally does not need to decode and combine every video stream into a single composite image. This reduces certain server-side processing requirements, although outbound bandwidth and participant device performance remain important.

Jitsi Videobridge and LiveKit are examples of SFU-based infrastructure.

Multipoint Control Unit

An MCU receives and processes media streams and may combine participants into composite video layouts.

This can simplify media handling for compatible endpoints and support some interoperability scenarios. However, media decoding and encoding can increase server resource consumption.

P2P vs. SFU vs. MCU

The architecture alone does not determine conference capacity. Performance also depends on codecs, resolution, frame rates, device capabilities, server resources, and network conditions.

Insight 2: Installing a Conference Server Does Not Mean Every Media Stream Passes Through It
Organizations sometimes assume that installing conferencing software internally means all communication stays on that server.
In reality, signaling, media transport, authentication, recording, and network traversal may use different components.
A P2P application may establish direct media connections, while an SFU-based system forwards streams through designated infrastructure. Some deployments also use TURN relays or external authentication services.
A private conferencing deployment should therefore be evaluated through its complete network and data flow.
The important question is where communication is processed and which services are required, not simply where the main web interface is installed.

Self-Hosted Video Conferencing Server Requirements

Server requirements vary considerably between products.

A lightweight P2P signaling application may need relatively modest resources, while an enterprise conferencing server supporting hundreds of participants, recording, and media processing may require dedicated hardware or a distributed deployment.

There is no universal combination of CPU, RAM, and bandwidth that guarantees a particular conferencing capacity.

CPU and Memory Requirements

CPU resources are used for application services, signaling, media handling, encryption, and, where applicable, video processing or recording.

Memory requirements depend on the number of running services, participant sessions, and media workloads.

For SFU-based systems, forwarding media can reduce the need for full server-side transcoding, but CPU and memory usage still grow with concurrency and enabled functions.

Recording, transcription, AI processing, and other optional services may require separate workers or additional machines.

Platform-Specific Server Requirements

The following examples use published vendor guidance rather than generic estimates.

BigBlueButton's released 4.0 series requires a dedicated Ubuntu 24.04 server, while the MiroTalk SFU specifications describe a smaller starting configuration. These differences reflect different products and workloads, not a direct comparison of how many users each server can support.

The published requirements are starting points for installation, not guarantees of participant capacity. A server meeting the minimum specifications may still need additional resources for demanding conference workloads.

Bandwidth Requirements

Network capacity is particularly important for real-time conferencing because each participant generates media traffic.

In an SFU architecture, the server receives streams and distributes selected media to other participants. As more users participate, outbound server traffic can become significant even if CPU utilization remains manageable.

For example, assume a hypothetical meeting in which 20 participants each publish a video stream averaging 1 Mbps.

If every participant receives streams from the other 19 participants without bandwidth optimization, aggregate server outbound traffic would be approximately:

20 participants × 19 received streams × 1 Mbps = 380 Mbps

This is a simplified theoretical model, not a production capacity estimate. Real systems use adaptive streaming, selective subscriptions, different resolutions, and other optimizations that can substantially change bandwidth consumption.

The example nevertheless illustrates why a conferencing server with sufficient CPU and memory may still experience problems when network throughput is inadequate.

Storage Requirements

A conferencing application without recordings may require relatively modest storage. Recording-enabled deployments can generate substantially larger data volumes, especially when conferences are frequent or long.

Administrators should estimate storage based on recording duration, encoding settings, retention policies, and backup requirements.

For example, recording 100 meetings per month at an average file size of 500 MB would generate approximately 50 GB of new recordings monthly.

The actual file size depends on recording format, resolution, duration, and media content.

Small, Medium, and Enterprise Deployment Scenarios

These categories are planning scenarios rather than fixed hardware classes. The correct server configuration depends on the conferencing product and actual workload.

How to Estimate Concurrent Capacity?

Capacity planning should begin with the maximum number of participants expected to communicate simultaneously.

A company with 1,000 registered employees may require infrastructure for only 100 concurrent users. Another organization with 300 employees may need all 300 to participate in a single interactive event.

Meeting distribution also matters. Ten conferences with ten participants each may create different media and administrative workloads from one conference involving 100 participants.

A reliable sizing process considers concurrent meetings, conference size, video resolution, screen sharing, recordings, and the location of participants.

Can Self-Hosted Video Conferencing Work Without Internet Access?

Yes. Self-hosted conferencing can operate without public internet access when the platform and all required dependencies support isolated-network operation.

Some products require external registration, license validation, public authentication services, remote TURN infrastructure, or third-party integrations. A system may also support offline meetings while relying on external services for optional functions such as transcription or software updates.

LAN and Private Network Conferencing

A LAN can connect employees within one facility, while a private WAN can connect different offices. A VPN may provide access to authorized remote users, depending on security policy and network configuration.

These environments can support conferencing without exposing the server directly to the public internet.

Air-Gapped Conferencing

An air-gapped network is intentionally isolated from external networks.

To operate in this environment, conferencing software must not depend on services outside the isolation boundary for normal communication. Organizations also need approved processes for license management, software updates, certificates, and maintenance.

TrueConf Server's full licensed edition is an example of a product with documented autonomous operation in suitable isolated networks. Other platforms may be configured for restricted environments, but compatibility must be verified across every required component.

Offline Deployment Requirements

An isolated conferencing system cannot accept public internet participants unless an authorized network connection exists.

Security and Privacy in Self-Hosted Video Conferencing

Self-hosting provides greater infrastructure control, but strong security still depends on correct implementation.

A privately operated server can expose sensitive information through weak authentication, outdated software, incorrect permissions, or improperly secured administration interfaces.

Security should therefore be evaluated across the complete communication environment.

Encryption in Transit

Transport encryption protects signaling and media traffic while it moves across the network.

Organizations should verify which protocols and configurations protect meeting content, browser access, and communication between infrastructure components.

Older conferencing endpoints may impose compatibility limitations that require particular attention.

End-to-End Encryption

End-to-end encryption is designed to prevent intermediary systems from decrypting protected content.

However, E2EE may limit functions that require server-side media access, including recording, transcription, mixing, or some interoperability scenarios.

OpenVidu Meet provides a concrete example: its documentation states that E2EE and server-side recording cannot be enabled simultaneously in the same room.

Identity Management

Enterprise conferencing systems may support corporate directories, SSO, and additional authentication measures.

These capabilities simplify access management when employees join, change roles, or leave the organization. Businesses should verify integration with their actual identity infrastructure rather than assume that support for a protocol guarantees compatibility with every directory configuration.

Recording and Data Retention

Meeting recordings may contain confidential documents, personal information, and commercially sensitive discussions.

Administrators must determine who can record, where recordings are stored, how long they are retained, and who may access or delete them. An internally hosted conferencing server does not automatically guarantee that every recording or transcription component is also internally operated.

Security Assessment Checklist

Insight 3: Self-Hosting and End-to-End Encryption Solve Different Problems
Self-hosting determines who operates and controls the communication infrastructure.
End-to-end encryption determines which systems and participants can decrypt protected meeting content.
A self-hosted conferencing server may process media internally to support recording or mixing. Conversely, an end-to-end encrypted service may protect content while relying on infrastructure operated by a third party.
Neither model automatically satisfies every security requirement.
Infrastructure control, content confidentiality, recording requirements, and administrative visibility should be evaluated separately.

How to Deploy a Self-Hosted Video Conferencing Server?

A successful conferencing deployment requires more than installing an application.

The infrastructure must support realistic media workloads, appropriate access controls, and reliable recovery procedures.

Step 1. Define Concurrent Usage

Estimate the maximum number of simultaneous participants and meetings.

For example, an organization with 2,000 registered employees may need capacity for only 150 concurrent participants, while a smaller company may regularly organize conferences involving nearly its entire workforce.

Document expected meeting sizes, video quality, screen sharing, recording, and guest participation.

Step 2. Select Infrastructure

Choose physical servers, virtual machines, private cloud resources, or customer-managed public cloud infrastructure.

Consider the operating-system requirements of the selected product, expected workload, geographical distribution, redundancy, and administrative resources.

Where vendor guidance provides minimum CPU, RAM, and bandwidth specifications, use those requirements as the initial baseline.

Step 3. Configure Networking

Prepare signaling and media connections, DNS, certificates, firewall rules, and network routing.

WebRTC deployments may require STUN or TURN services depending on topology. Administrators should verify that the conferencing media ports are accessible through intended network paths.

Step 4. Install the Platform

Follow official installation documentation for the selected release.

Depending on the product, deployment may involve Linux packages, Docker containers, virtual machines, or dedicated installation tools.

Avoid applying instructions from older software versions without checking operating-system and dependency compatibility.

For BigBlueButton 4.0, this means installing the system on a suitable Ubuntu 24.04 server instead of attempting a direct in-place upgrade from BigBlueButton 3.0. Existing installations should use a planned migration process that preserves recordings and tests integrations.

Step 5. Configure Authentication

Create administrator accounts and establish meeting access policies.

Where supported, integrate the conferencing system with the organization's identity provider. Define who can create meetings, invite guests, record conferences, and manage administrative settings.

Step 6. Configure Recording and Optional Services

Identify where recordings will be stored and how long they must be retained.

If transcription, streaming, AI processing, or integration services are required, include their infrastructure and network dependencies in the deployment.

For restricted environments, verify that these services operate within the approved boundary.

Step 7. Conduct Performance Testing

Test realistic participant numbers and meeting combinations.

Include screen sharing, multiple cameras, guest access, mobile clients, recording, and existing hardware terminals where relevant.

Monitor CPU usage, memory, bandwidth, packet loss, and connection stability. A five-person pilot meeting does not establish that a platform can handle hundreds of concurrent participants.

Step 8. Prepare Monitoring and Recovery

Configure monitoring, backups, update procedures, and documented recovery processes.

For critical environments, evaluate redundant components and test the recovery plan before production use.

Deployment Checklist

How Much Does Self-Hosted Video Conferencing Cost?

The total cost depends on licensing, server infrastructure, expected capacity, administration, and support.

Open-source conferencing platforms may be available without conventional per-user subscriptions, but they still require hosting, maintenance, bandwidth, and technical expertise.

Commercial products may use server licenses, registered-user subscriptions, concurrent connection licensing, or additional fees for specific capabilities.

The most useful comparison considers total cost over several years.

Illustrative Three-Year Cost Comparison

Consider an organization with 200 employees evaluating two hypothetical conferencing approaches.

The cloud service charges $12 per user per month.

The self-hosted system requires $8,000 annually for licensing and support, $6,000 for infrastructure, and $5,000 for administration and maintenance.

In this illustrative scenario, the self-hosted approach costs $29,400 less over three years.

These figures are hypothetical and do not represent a vendor quotation, an industry average, or guaranteed savings. The calculation assumes stable licensing, user numbers, infrastructure expenses, and support requirements. Migration costs, major hardware replacement, unusual bandwidth expenses, and additional services are excluded.

Higher administrative costs or additional infrastructure could reverse the result.

Insight 4: Concurrent Usage Matters More Than Registered Employee Count
Server sizing is often misunderstood because businesses focus on how many employees may use the conferencing platform.
However, infrastructure consumption is driven primarily by simultaneous activity.
A company with thousands of registered employees may have modest capacity requirements if only a small number participate concurrently. A smaller organization may need substantial server and network resources if it regularly conducts large interactive conferences with high-resolution video and screen sharing.
Recording and streaming can add further processing requirements.
For capacity planning, peak concurrent meetings and participants are generally more useful than total registered users alone.

Common Mistakes When Choosing Self-Hosted Video Conferencing

One common mistake is selecting a platform exclusively because the software is free to install. The organization may later discover that production operation requires additional media servers, recording components, monitoring tools, or specialist support.

Another mistake is overlooking differences between software versions. A deployment guide written for an older release may no longer describe a supported operating system or migration path. BigBlueButton's transition to Ubuntu 24.04 in version 4.0 provides a practical example of why version-specific documentation matters.

Businesses should also avoid treating a small pilot as evidence that a system can handle enterprise-scale workloads. Realistic performance testing is necessary to understand concurrent capacity, network dependencies, and the effects of recording or screen sharing.

Finally, technical teams should consider the complete operational environment rather than only the conferencing application. Authentication, media relays, storage systems, and maintenance processes can all influence availability and security.

Which Self-Hosted Video Conferencing Platform Should You Choose?

The appropriate product depends on the organization's communication needs, existing infrastructure, and operational resources.

Pexip Infinity vs. TrueConf Server

Both platforms support compatible SIP and H.323 equipment, but their broader positioning differs.

Pexip Infinity is particularly relevant when the main objective is interoperability between existing professional video endpoints and distributed conferencing infrastructure.

TrueConf Server is more appropriate to evaluate when an organization also wants persistent corporate messaging, user directories, and an integrated internal communication environment.

A company focused on preserving conference room equipment may prioritize Pexip's interoperability architecture. Another company replacing several internal communication tools may place greater value on TrueConf's combination of conferencing and messaging.

OpenVidu Meet vs. LiveKit

These products also serve different development needs.

OpenVidu Meet provides a meeting application that can be embedded and controlled through APIs. Developers can integrate conferencing without building the entire meeting interface from the beginning.

LiveKit primarily provides programmable media infrastructure. It is appropriate for teams that want more control over the application experience and have the resources to develop the necessary interfaces and business workflows.

Jitsi Meet vs. MiroTalk

Jitsi Meet provides an established open-source meeting application with a defined conferencing architecture centered on Jitsi Videobridge.

MiroTalk offers separate applications based on peer-to-peer, SFU, and broadcast models, allowing developers to select the approach that fits their project.

For organizations seeking a general-purpose meeting application, Jitsi may be simpler to evaluate as a single platform. For developer-led projects requiring a specific communication architecture, MiroTalk's product family provides additional choices.

Ultimately, the selection process should include a pilot deployment using realistic meeting sizes, authentication requirements, network conditions, and business workflows.

Conclusion

Self-hosted video conferencing allows organizations to operate meetings on infrastructure they control, providing flexibility over server placement, network access, communication data, and integration with existing IT systems. Jitsi Meet, Nextcloud Talk, OpenTalk, BigBlueButton, OpenVidu Meet, Pexip Infinity, TrueConf Server, LiveKit, and MiroTalk address different needs, from open-source browser meetings and virtual classrooms to enterprise communication and programmable media infrastructure. Choosing between them requires understanding whether the organization needs a complete workplace communication platform, specialized conferencing software, or developer-oriented media services.

The main trade-off is operational responsibility. Self-hosted systems can support data sovereignty, customization, and private-network communication, but organizations must manage infrastructure, security, updates, monitoring, and recovery. Selecting the right platform requires evaluating concurrent capacity, current server specifications, network dependencies, integration requirements, and total cost of ownership. The strongest solution is the one that reliably supports the organization's communication needs within its technical, security, and operational constraints.

FAQ

What is the best self-hosted video conferencing software?

The best platform depends on the organization's requirements. Jitsi Meet is suitable for customizable browser meetings, BigBlueButton specializes in education, Pexip Infinity supports enterprise video interoperability, and TrueConf Server combines private conferencing with corporate messaging. Organizations should compare infrastructure, security, capacity, and integrations before choosing a product.

Can I host my own video conferencing server for free?

Yes, platforms such as Jitsi Meet and BigBlueButton provide open-source software that can be deployed on customer-managed servers. However, infrastructure, bandwidth, maintenance, administration, and support still create costs. Other self-hosted products may require commercial licensing for certain deployment models or capabilities.

What are the minimum server requirements for self-hosted video conferencing?

There is no universal minimum because requirements depend on the platform and workload. For example, BigBlueButton 4.0 recommends a dedicated Ubuntu 24.04 server with eight CPU cores, 16 GB RAM, and at least 250 Mbps symmetrical bandwidth, while MiroTalk SFU lists an entry-level configuration of two vCPU and 4 GB RAM. Organizations should follow the documentation for their selected product version and validate capacity through testing.

Can self-hosted video conferencing work without internet access?

Yes, if the conferencing software and all required dependencies support isolated operation. The organization must provide internal networking, authentication, media transport, and appropriate licensing. Self-hosting alone does not guarantee that every feature works without public internet connectivity.

Is self-hosted video conferencing more secure than Zoom or Microsoft Teams?

Self-hosting provides greater infrastructure control but does not automatically guarantee stronger security. Protection depends on encryption, authentication, network configuration, software maintenance, and administrative policies. Security should be evaluated according to organizational requirements rather than hosting location alone.

What is the difference between self-hosted and on-premises video conferencing?

Self-hosted video conferencing means that an organization operates conferencing software on infrastructure it controls. On-premises conferencing specifically refers to infrastructure located within the organization's own facilities or data centers. Self-hosted software can also run on customer-managed cloud infrastructure.

Can external guests join a self-hosted video conference?

Many self-hosted platforms support external participation through browsers, mobile clients, or compatible conferencing terminals. Guest access depends on authentication policies, network configuration, and product capabilities. Isolated conferencing environments require an approved connection path for external participants.
