Question Log¶

Q1 — Can Flask ever be used asynchronously?¶

Asked: 2026-06-09 Status: unanswered

The module says Flask is WSGI-only. But I have seen async def in Flask routes online. Does Flask support async?

Q2 — Why does FastAPI generate docs automatically but Flask does not?¶

Asked: 2026-06-09 Status: unanswered

What is it about FastAPI's design that lets it generate OpenAPI docs without any extra library or configuration?

Q3 — Is there a performance difference between WSGI and ASGI for a simple JSON endpoint with no I/O?¶

Asked: 2026-06-09 Status: unanswered

If my endpoint just reads from memory (no database, no network calls), does switching from WSGI to ASGI give any performance benefit?
