You don't have to run a separate FastAPI server to handle additional webhooks anymore! With the January Streamlit 1.53 release, you can now mount a Streamlit app over Starlette, effectively replacing Tornado. However, the more interesting part is, you have programmatic access to the Starlette instance to add your own endpoints, middleware and error handlers! This enables so many new use cases: Custom endpoints: move your ML library to a Starlette endpoint, create a Stripe endpoint to catch...

Hello Datafan, happy 2026, prosperity, determination and joy for the new year! I produced a short video for Streamlit 2026 features I'm looking forward to the most.

Ever needed to uniquely identify users for your Streamlit app through an email/Google single sign-on page?

I created a fake Streamlit store app with a sign up button for you to play with Streamlit native authentication through Auth0, an authentication as a service platform that makes it easier to manage multiple social logins like Google, X/Twitter or Linkedin. The app is still live on...

A week ago, I was sitting in an airport cafe, ready to wait 3 hours for a plane from Manchester back to Paris, followed by a 4 hour train trip to the South of France. Those long business trips are my usual gateway to catch up on "things I want to learn but never have time to". I would load up on hour-long entrepreneurship podcasts and rediscover books about Marketing from Seth Godin. But the morning in this airport cafe, I stumbled upon Next.js's File-based routing system.

I just heard the Solara team unveiled a new platform to deploy Dash, Solara and Streamlit apps! py.cafe, to share Python apps while on a coffee chat WASM Platforms py.cafe is a new WebAssembly powered solution to host and share Python apps through the power of Pyodide. This is a fancy way to say you can implement a Streamlit meme app in your browser, then copy the URL and send it to a friend, colleague or the CEO of your dream company. Just like this link (hopefully this long weird URL is not...
