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.
