The $0 Tech Stack That Powers a Complete SaaS Platform

When I set out to build a SaaS platform, I had two constraints: no budget and no time to waste.

After evaluating dozens of combinations, I landed on a tech stack that costs exactly $0 to run in production — while handling authentication, database, storage, payments, and deployment.

Here's the breakdown:

Frontend: Next.js 15 + TypeScript

• App Router for file-based routing
• Server Components for performance
• Built-in API routes (no separate backend needed)

Styling: Tailwind CSS

• Utility-first CSS that scales
• Dark mode support out of the box
• Zero runtime overhead

Backend & Database: Supabase

• PostgreSQL database (free tier: 500MB)
• Built-in authentication (email, OAuth)
• Real-time subscriptions
• Storage for file uploads
• Auto-generated REST API

Payments: Creem / Stripe

• One-line integration
• Supports subscriptions and one-time payments
• Handles taxes and compliance

Deployment: Vercel

• Push to deploy from GitHub
• Free tier includes SSL, CDN, and edge functions
• Preview deployments for every PR

The Result: PubliFlow SaaS Starter Kit

I packaged everything into a production-ready starter kit that includes:

• ✅ Authentication (sign up, login, OAuth)
• ✅ Dashboard with data visualization
• ✅ Payment integration (subscriptions + one-time)
• ✅ Landing page template
• ✅ Email templates
• ✅ SEO optimization
• ✅ One-command deployment

The goal: Go from git clone to paying customers in 7 days, not 7 weeks.
