Realtime multiplayer Python in the docs (SSE, not WebSockets) (opens in new tab)

Stario is a Python 3.14+ framework for building web apps that scale with you — from static pages and simple forms to realtime, multiplayer experiences. The same pieces stay explicit as experiments grow into products: routes as data, handlers as plain async functions, HTML composed in Python, optional Datastar for live UI, and built-in telemetry so you can see what matters.
