Building a SaaS from scratch is exciting — until you realize you have to rebuild auth, billing, payments, and AI integration every single time.
I got tired of it. So I built a complete, production-ready starter kit that includes everything you need to launch an AI-powered SaaS in days, not weeks.
What's Inside
Next.js 15 (App Router + Server Actions)
The latest and greatest from the React ecosystem. App Router for nested layouts, Server Actions for form handling, React Server Components for optimal performance.
Authentication with JWT
HttpOnly cookies, bcrypt password hashing, login/signup flows, protected routes — all built in and ready to customize.
Stripe Subscriptions
Monthly and yearly billing with Stripe Checkout. Webhooks for subscription status changes, automatic upgrades/downgrades. Also handles one-time purchases.
OpenAI Streaming Integration
Chat with streaming responses, credit-based usage limits so you don't get surprise bills. Swap in any OpenAI-compatible API (Azure, Ollama, etc.).
Admin Dashboard
User management, usage analytics, content moderation — everything you need to run your SaaS.
SQLite Database
Zero config, no external database needed. Perfect for getting started. Swap to PostgreSQL when you scale.
Docker + One-Click Deploy
Containerized for development and production. Deploy to Vercel with a single click.
The Tech Stack
| Layer | Technology |
|---|---|
| Framework | Next.js 15 (App Router) |
| Auth | JWT (httpOnly cookies) |
| Database | SQLite (via better-sqlite3) |
| Payments | Stripe (subscriptions + webhooks) |
| AI | OpenAI streaming + credit limits |
| Styling | Tailwind CSS |
| Deployment | Docker / Vercel |
Why I Built It
Every time I started a new SaaS project, I spent the first 2-3 weeks on the same boilerplate: auth, database setup, payment integration, admin panel. It's tedious, error-prone, and doesn't add any unique value to your product.
This kit encodes all those patterns so you can jump straight to what makes your product special — the AI features, the UX, the marketing.
Who Is This For?
- Indie hackers who want to ship fast
- Agencies building custom SaaS for clients
- Developers launching their first paid product
- Non-technical founders who want a ready-to-deploy solution
