Key Considerations
Important factors to keep in mind when building a python backend.
- Python GIL limits CPU-bound concurrency
- Virtual environments are essential (use Poetry or uv)
- FastAPI is async, Django is sync by default
- Type hints improve code quality significantly
- Deployment needs WSGI/ASGI server (Uvicorn, Gunicorn)
When to Avoid This Stack
This stack might not be the best choice for the following scenarios.
- Real-time applications needing high concurrency
- Mobile apps (use JavaScript/TypeScript)
- Teams without Python expertise
