Not sure if we should use DRF or FastAPI. I hear many good things about FastAPI, but it doesn't seem to have a big community. Most important things for us: - speed - ease of development - scalability & security

We're likely going to use MongoDB, so not sure if that changes anything. Would appreciate any help!

I'm a Data Engineer, looking to build some web apps in my spare time, especially on weekends. I'm debating between choosing Django over FastAPI. What I am pondering are performance, development speed, ease of management, scalability, and support if I ever need to use another frontend framework (eg React). Please help me with advice, I would appreciate it!
