구성을 멈추고, 배포를 시작하세요: 나의 궁극적인 FastAPI + React SaaS 스택

Source: Dev.to

Hi everyone! 👋

I’m Mehdi, a Full Stack Dev & DevSecOps enthusiast.

We all know the feeling: you have a great SaaS idea on a Friday night, open your IDE, and then spend the entire weekend configuring Docker, fighting CORS errors, setting up Authentication, and verifying Stripe Webhooks. By Sunday evening the infrastructure is ready, but the motivation for the actual product is gone. 📉

I got tired of this cycle, so I spent the last few weeks building the ultimate opinionated boilerplate to solve it once and for all.

🛠 The Tech Stack

I chose this stack for one reason: Speed & Scalability.

1. The Backend: FastAPI (Async) ⚡️

• Fully Async: Leveraging Python’s async/await for high performance.
• Type Safety: Uses Pydantic for validation (fewer bugs in prod).
• Auto Documentation: Swagger UI is generated automatically.

2. The Frontend: React + Vite + TailwindCSS 🎨

• Vite: Instant server start; no more waiting for Webpack.
• TailwindCSS: Rapid UI development without leaving your HTML.
• Context API: Simple, clean global state management for Auth/User data.

3. The Infrastructure: Docker & Supabase 🐳

• Docker Compose: The whole app (Frontend + Backend + Celery + Redis) spins up with a single docker‑compose up command.
• Supabase: Provides PostgreSQL and Authentication handling, saving tons of backend logic.

4. The Painful Stuff (Solved) 😅

• Stripe: Complete implementation with webhook handling and secure signature verification.
• Celery + Redis: Background tasks (sending emails, processing data) without blocking the main API.
• Protected Routes: Custom middleware to lock down endpoints based on user roles.

🚀 Why I built this

I built this primarily for myself, to stop reinventing the wheel. I realized other developers might want to save those 50+ hours of setup time too. You can definitely build this stack yourself using the list above (it’s a great learning exercise!), but if you want to skip the headache and start coding product features right now, I packaged the whole code into a clean, documented starter kit.

👉 Production‑Ready SaaS Starter Kit (paid template to support maintenance; costs less than one hour of billable time).
