According to the Python Developers Survey 2025, FastAPI is currently the most popular web framework. Check out this mini doc by @CultRepo about its creator.

Sebastián Ramírez (@tiangolo) built one of the fastest-growing frameworks in tech & people still mostly ask about the moustache. So we got him to explain it once and for all! 🥸 He also features in our latest mini-doc: The Rise and Rise of FastAPI, out now on our YT channel 👀



The full-stack-fastapi-template now uses @shadcn / ui (with @tailwindcss) for the frontend 🚀🎉 There's still dark mode too, and all the nice things 🦇 Thanks @alejsdev ! 🙌 github.com/fastapi/full-s…

FastAPI 0.124.0 comes with better server error tracebacks. ✨ Before, if the app sent invalid data back, the server error logs would not show where the problem was. 😔 Now it shows the (clickable) file, line, function, and path operation. 📢 Thanks @savostrowski! 🙌

Another FastAPI bug-fix release, 0.123.9 🐛 This fixes more edge cases around OpenAPI and OAuth2 scopes 🔒️ It required a considerable internal refactor, so now the code is more robust and less error-prone. 😎 github.com/fastapi/fastapi

The Rise and Rise of FastAPI



Mooore releases! FastAPI 0.123.8 🥞 🐛 Fix a bug in the OpenAPI schema generated for security schemes using OAuth 2 scopes, when using different scopes at the router or path operation level github.com/fastapi/fastapi


FastAPI will drop support for Python 3.8 in the next days 🔥


Now FastAPI 0.123.7 ☕️ 🐛 Fix corner cases in stringified annotations in Python 3.10+ (a.k.a. from __future__ import annotations)


Here's FastAPI 0.123.6 🍰 🐛 Fix support for functools wraps, partial, in async and regular functions, for path operations and dependencies, including with yield, classes, callables, etc. github.com/fastapi/fastapi


Here's another FastAPI release, 0.123.5 🎁 Several related fixes and improvements, support for functools wraps, partial 🚀 github.com/fastapi/fastapi


How many releases do you like to have in a day? Here's more: 0.123.3, 0.123.4 🥞 Granular releases, so you can get the latest, but if something doesn't work for you for some reason, you can still get some of the fixes in the previous release. ☕️


More bug-fix releases for you! 🐛 FastAPI 0.123.1 and 0.123.2 🍫 fastapi.tiangolo.com/release-notes/

There's a mini-documentary about @FastAPI coming out in a couple of days 🤩 Made by @CultRepo, the same team behind the Python documentary 🐍🎉

We've been working on a mini-doc about how @FastAPI actually came to be… and the story is not quite what we expected... A homeschool kid from Colombia (hi @tiangolo 👋), a rejected GitHub idea and a framework that no one was really supposed to notice. Coming Thursday!! 🤩



FastAPI 0.123.0 🚀 This (and 0.122.1) handles a bug in caching dependencies when using OAuth 2 security scopes. 🐛 github.com/fastapi/fastapi


Have you read the FastAPI docs enough for this to happen? 🎸

skimming through fastapi docs and just got rick rolled lol @FastAPI i love you



Long-awaited, FastAPI 0.122.0 🎁 🐛 Security classes now return 401 on errors instead of 403 They include sensible WWW-Authenticate headers to stay spec-compliant 🤓 If your code depends on 403 errors, you can override this: fastapi.tiangolo.com/how-to/authent… Thanks YuriiMotov! 🙌
