Your FastAPI is safe 🔒

Today, FastAPI was incorrectly flagged as malicious by automated tooling from a large company, among several other packages.

FastAPI was not compromised. It was a false positive.

We were not contacted before publication. This should not happen to OSS.

After a thorough ranking of moustaches, it is decided:

@tiangolo will give the opening keynote at FastAPI Conf 🤓

(the fact that he created FastAPI and is writting here in third person has nothing to do with it)

Join the waiting list 🫰🏼

It seems @FastAPI's downloads have more than doubled since early this year 📈

From 8M to 19M per DAY 💥

Maybe because coding agents are so good at writing Python and FastAPI, don't really know 🤔

We wanted @FastAPI Conf to be stellar. ✨

So we brought in @hype_fi, one of the main people behind @pyconit, an event among the most renowned Python conferences in the world.

This is going to be good. Join the ticket waitlist. 🎟️
