Question 1

How do I deploy FastAPI to a VPS?

Accepted Answer

Deploy FastAPI using Uvicorn as the ASGI server with Nginx as a reverse proxy. Run "uvicorn main:app --host 0.0.0.0 --port 8000" in production, or use Gunicorn with Uvicorn workers: "gunicorn main:app -k uvicorn.workers.UvicornWorker". Use systemd for process management.

Question 2

Should I use Uvicorn or Gunicorn for FastAPI?

Accepted Answer

Use Gunicorn with Uvicorn workers for production: "gunicorn -k uvicorn.workers.UvicornWorker main:app". This gives you Gunicorn's process management with Uvicorn's async performance. For development or simple deployments, pure Uvicorn works fine.

Question 3

How do I enable HTTPS for FastAPI?

Accepted Answer

Handle SSL termination at the Nginx level rather than in FastAPI. Configure Nginx with Let's Encrypt certificates and proxy to your FastAPI application. This is more efficient and follows best practices for production deployments.

Question 4

What makes FastAPI good for self-hosting?

Accepted Answer

FastAPI is extremely efficient due to async support and minimal overhead. It generates OpenAPI docs automatically, making API development and documentation seamless. The framework is well-suited for VPS deployment with excellent performance per dollar spent.
