FastAPI + PostgreSQL Production-Ready API Starter Kit (Async SQLAlchemy, JWT, Docker)

Stop burning hours wiring FastAPI and PostgreSQL together. Start shipping a secure, production-ready API in under 10 minutes.

You know the pain: every tutorial shows a different pattern, async SQLAlchemy breaks the moment you add real traffic, Alembic migrations fail silently, JWT examples are insecure, and your “simple Docker setup” behaves differently in local vs production. You just want a backend that works so you can focus on features instead of fixing hidden traps.

This starter kit gives you a complete FastAPI + PostgreSQL backend with async SQLAlchemy, secure JWT auth, Redis rate limiting, and a reproducible Docker environment. Every file is production‑ready and pre‑wired, so you can start coding your app instead of configuring infrastructure.

What's Included:
- Fully structured FastAPI project with clean module layout
- Async SQLAlchemy setup using the correct session pattern to prevent connection leaks
- Alembic migration folder with working first migration and env config
- JWT auth flow with access + refresh tokens, hashing, blacklist storage, and invalidation routes
- Redis‑based rate‑limiting middleware with dependency overrides
- User model, auth routes, and password hashing using recommended security practices
- Environment‑specific settings system for local, staging, and production
- Dockerfile and docker-compose stack for app, PostgreSQL, and Redis
- Preconfigured tests showing how to test async DB and auth flows

Built from patterns used in production SaaS deployments handling real authentication workloads, not toy examples. Every component was shaped by fixing the exact failures that occur when FastAPI apps move from local development to real users.

Who This Is For:
- Python developers building a new SaaS MVP and tired of wiring auth and DB layers from scratch
- Freelancers who need a reliable FastAPI baseline they can reuse across client projects
- Engineers migrating from Flask or Django who need a correct async setup without guessing

Who This Is NOT For:
- Developers who only need a toy or learning project
- Teams who already maintain an internal FastAPI boilerplate

Guarantee: If this kit doesn’t save you at least 6 hours of setup time, email me for a full refund—no questions asked.
