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.

I found a ui bug on your site
I tried to zoom out I that happened
Zooming out is a classic way to expose hidden responsive layout flaws, especially when containers rely on fixed pixel widths instead of relative units. I need to track down which specific media query is failing to handle that extreme viewport scaling. Could you let me know which browser and screen resolution you were using when the UI broke? That context will help me isolate and fix the overflow issue much faster.
