FastAPI

Big news: the first-ever ✨ FastAPI Conf ✨ is coming! 📍 Amsterdam 📅 October 28 Meet the FastAPI team, connect with developers ☕️ 🎟️ Join the waitlist for early ticket access: fastapiconf.com

Bug fix release 0.137.1 🐛

FastAPI 0.137.0: a big internal refactor for routers 🏗️ You are probably not affected, unless you are iterating on the internal router.routes, then check the docs 📝 If you use any third-party package that modifies FastAPI's internals and it stops working, let them know 🤓

Can you imagine being there? 🤩 Surrounded by FastAPI developers and maintainers from around the world. Watching the best FastAPI talks you could ask for 😎 FastAPI Conf will happen at Westergas, in Amsterdam 🌷 Join the waiting list 🎟️ fastapiconf.com

Have you found the easter egg in the FastAPI Conf website? 🥚 What's your highest score? 🕹️ fastapiconf.com

@BloodcrownDren Now you have to watch Rick and Morty 😎

WTF @FastAPI 🤣🤣

The unspoken moat: @FastAPI + Python didn't just speed up deployment. They merged two jobs into one. When your ML person ships the API directly, knowledge doesn't get lost in handoff. That's not efficiency, it's architecture as competitive advantage.

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 🫰🏼 fastapiconf.com

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 🤔

FastAPI's massive global community now has a space where the people building it and the people running it in production can meet and talk directly 🎙️ Some of the best insights come from these in-person chats ☕️ Join the FastAPI Conf waiting list 📩 fastapiconf.com

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. 🎟️ fastapiconf.com

Go to your @FastAPI project and run: uvx library-skills Teach your AI coding agents to use FastAPI properly. 😎 library-skills.io

@RainzeeWang @code @tombi_toml Yes 😎

@FastAPI @code @tombi_toml so with entrypoint i can just fastapi dev to run ？

Now there's autocompletion and docs in pyproject.toml for FastAPI 🎉 [tool.fastapi] entrypoint = "main:app" Make sure you have a modern editor and TOML plugin, like @code with @tombi_toml 🤓
