At some point this month, Typer reached 20k GitHub stars ⭐️ Also, you can start getting excited, @oxykodit.bsky.social is finishing implementing Pydantic support 🤩 Go build CLIs with Typer, your users and agents will thank you. github.com/fastapi/typer

Tell me something good you've done for someone else recently

Meet the FastAPI Conf master of ceremonies: @judy.co.uk 🎙️ fastapiconf.com/speakers/#mc

This is how you party in nerd 🤓👾

Python 3.15 has too many exciting things for a single post. 🐍🤩

In FastAPI 0.143.0, the OpenTelemetry auto exporter is now opt-in, enable it with the env var FASTAPI_OTEL_AUTO_CONFIGURE=true This handles some use cases like Nvidia's NeMo LLM training framework In @fastapicloud.com it just works by default ✨ fastapi.tiangolo.com/advanced/ope...

Welcome Polar as a Gold Sponsor of FastAPI Conf! 🎉 Polar handles payments, subscriptions, and sales tax so you can focus on building. Thank you for being part of the inaugural FastAPI Conf! 🤝 Oct 28, Amsterdam fastapiconf.com#supported-by

SQLAlchemy 2.1 was released 2 weeks ago, it adds several typing improvements and has @psycopg's latest version as the default for Postgres 🎉 SQLModel 0.0.48, just released, adds support for it, so you can get the new cool stuff by default. 🥳 sqlmodel.tiangolo.com

Welcome Redis as a Gold Sponsor of FastAPI Conf! 🎉 Redis helps developers build fast applications with caching and real-time data. Thank you for being part of the inaugural FastAPI Conf! 🤓 Oct 28, Amsterdam fastapiconf.com#supported-by

Our first Gold Sponsor for FastAPI Conf is Runpod! 🎉 Runpod provides cloud GPUs for training and deploying AI models. Thank you for being part of the inaugural FastAPI Conference! 🙌 Oct 28, Amsterdam fastapiconf.com#supported-by

I think this is big. 🌠 FastAPI's objective is to provide what you always need for real prod apps. And not provide what you don't. You always want metrics, there's just not enough time to always set it all up. Now it's just there, by default.

The new official Redis SDK for FastAPI is so cool! Come and see it in action. 🚀

I will keep reviewing and adjusting any AI generated code until the models can consistently one-shot produce something I would consider acceptable. I haven't been able to just "trust the model". But anyway, trust is earned, applies to humans, companies, products, AI.

SQLModel 0.0.47 adds direct support for Postgres, MySQL, MariaDB 🐘 sqlmodel.tiangolo.com (It was already supported via SQLAlchemy, but now all the SQLModel tests run with each DB)

Talk update 🎙️ François Voron is bringing a new topic to FastAPI Conf 2026: You don’t need /v2: API Versioning with FastAPI Come and learn the latest tricks from Polar.sh, including a custom SDK for clients, based on the new FastAPI versioning system 🤖 fastapiconf.com/speakers/#fr...

In FastAPI Cloud, you get the fastest Python distribution for your FastAPI apps by default ⚡️ (x.com/charliermars...)

A couple of SQLModel releases in a row, latest is 0.0.45 ✨ Potentially breaking change: datetime now uses UTC by default (as it should be) 🚨 sqlmodel.tiangolo.com/advanced/dat...

Very interesting idea by @seldo.com to solve open source funding. Have PyPI and npm be the ones to charge corporates for downloads and distribute it to maintainers. I like several aspects, I would pay if I was charged. seldo.com/posts/nobody...

I bet we'll get many "simple" tricks that are not always obvious and leave you thinking "wait, you can just do that?" ☕️

Welcome back dear softmax, what jev been doin?

That's crazy!!! (as @marcelotryle.bsky.social would say) It's always very fun seeing Marcelo live, don't miss it. 🤙

Want your FastAPI Conf T-shirt in your size? 👕 Get your ticket and select your size by September 20! Tickets bought after that still include a T-shirt, but your size won't be guaranteed. Join us in Amsterdam! 🚲 fastapiconf.com

I'm still amazed that @fastapi.tiangolo.com helps scientists around the planet access space telescope data. ✨ I'm really looking forward to this talk. 🤩

You really want to get more insights into how a mastermind like this thinks about code and AI. I definitely do.

The FastAPI full-stack template now comes with the agent skills (uvx library-skills) for FastAPI and SQLModel built in. You can create your project, point your agent to it, and it will be able to write modern and correct code with the libararies. github.com/fastapi/full...

Come and learn how typing.Annotated works underneath from François Voron at FastAPI Conf. 🤓 Learn things you won't learn anywhere else. Join us in Amsterdam! 🚲️ fastapiconf.com/speakers/#fr...

A few days ago, the Early Bird tickets for FastAPI Conf got officially SOLD OUT! 🐦️ The response has been incredible. 🚀 If you’ve been thinking about joining us, don’t wait too long. 🏃‍♀️ Get your ticket: fastapiconf.com

Finally, I can guide you to build a proper full-stack app, from scratch, until it's deployed to your users, in minutes. 🤏🚀 I've been working towards this for the past 10+ years. 😅 Now it's about continuous improvements and more planned features. 😎

I didn't see this coming. 👀 I always thought @fastapi.tiangolo.com should have more followers than me individually, but it hadn't happened yet. This makes more sense to me. 😅

One of the few friends I asked if it would make sense to build a cloud for @fastapi.tiangolo.com, in 2023 was @dynamicwebpaige.bsky.social She said "you have to, not only for humans, but for agents" This was way before we all used agents for coding And now at FastAPI Conf! So cool. Full circle. 💃

The full-stack FastAPI template now serves the React - TanStack frontend with FastAPI ✨ One single app, one single deployment, one single domain. No CORS fights and debugging. github.com/fastapi/full...

There are only a few early bird tickets left for FastAPI Conf 🤏 🐦 fastapiconf.com

A bunch of improvements in development workflows and style for emails from Alejandra in the full-stack-fastapi-template, so you can create your app with the best baseline. ✨

Did you see the famous talk "Pydantic is all you need"? And how that ended up in AI Labs providing structured output? It seems Jason Liu is all you need! 🙌 (And we'll all keep making references to the Transformers paper until morale improves).

This is the last week to get your early bird tickets for FastAPI Conf, hurry! 🏃 Prices increase next week. 📈 Do you need to convince your boss? Use our convincifyinator: fastapiconf.com/convince-you...

I'm from Colombia 🇨🇴 It was hit by a heavy earthquake these past days. The damage is overwhelming, the loss unmeasurable. Many places I remember are now destroyed. Wishing strength for those who lost, and those helping others. Can you donate too? ⛑️ ayuda.cruzrojacolombiana.org

FastAPI Conf news! 📢 @marcelotryle.bsky.social , maintainer of Starlette and Uvicorn, the web components behind FastAPI, will join us as a speaker in Amsterdam! 🙌 Get your tickets: fastapiconf.com

Here's the full-stack-fastapi-template 0.12.0 🎁 More modern, simpler, easier. Too many improvements to fit here, but let's start: You can now simply click the "Use this template" button in GitHub to create a new repo, possibly private. ✨ github.com/fastapi/full...

Python is the most reviewable language 🐍

Remember this image from the James Webb space telescope? Wanna know how the science data here is transferred to scientists around the world using @fastapi.tiangolo.com ? And also the images we will see in January from The Roman Telescope (about to be launched). Come to FastAPI Conf. 🌠

Coding agent thingies extending what you can research and build combined with giving them FastAPI Cloud to deploy feels like such a superpower. First print("hello world") vibes ✨ I just replaced 50 GitHub personal access tokens with 3 apps, while making everything more secure.

Early Bird tickets for FastAPI Conf are still available, but only until August 23 🐓 Get yours before prices go up! 🎟️ You don't want to miss what we'll announce there 🤫 fastapiconf.com

Two hard problems in computer science: 1. cache invalidation 2. naming things @nucleonjohn.bsky.social is (very cleverly) taking care of the cache invalidation for you, so you can focus on naming your app. 🤓 You code. We cloud. ⚡️
