If you build automation workflows on SaaS platforms like Zapier or Make, you have likely hit that painful threshold: your workflows scale up, and suddenly the monthly subscription bill skyrockets.
When dealing with AI agents, multi-step data pipelines, or high-volume Webhooks, cloud task limits quickly become a bottleneck.
That is why thousands of developers are switching to self-hosting n8n.
With a self-hosted instance, you get zero task limits, zero per-execution fees, and 100% data privacy. Best of all, you can run it right on your local Windows 10 or 11 PC using Docker.
Why Self-Host n8n on Windows?
- Unlimited Executions: Run millions of workflow steps every month without paying extra.
- Local AI Integration: Connect n8n directly to local LLMs (like Ollama running Gemma or Llama 3) on your GPU at zero latency.
- Total Privacy: Credentials, database keys, and webhooks stay entirely inside your private network.
The Core 4-Step Setup Overview
1. Enable WSL 2 (Windows Subsystem for Linux)
Instead of heavy virtual machines, Docker on Windows relies on WSL 2 for native Linux performance. A single PowerShell command sets it up:
wsl --install
2. Configure Docker Desktop
Install Docker Desktop with the WSL 2 backend enabled. This gives you the container runtime and docker compose tools needed to orchestrate n8n seamlessly.
3. Production Stack with PostgreSQL
While SQLite works for small tests, a production setup pairs n8n with a dedicated PostgreSQL container to handle concurrent workflow executions without locking database files.
4. Connect Local LLMs via host.docker.internal
When n8n runs inside a Docker container, it can talk directly to your Windows GPU's Ollama instance using the special hostname:
[http://host.docker.internal:11434](http://host.docker.internal:11434)
