make the web feel alive

Turn any element into a live, shared one with a single attribute — no backend required.

toggles for everyone live!

Communal by default. Shared state, presence, and cursors out of the box — lived-in spaces instead of solitary feeds.
Library-agnostic, fast, expressive. Works with plain HTML, React, or any framework. One attribute turns an element live.
No backend to run. Real-time sync and persistence are handled for you — just deploy your static site.
Extend it to anything. Ship your own capabilities with can-play when the built-ins aren’t enough.
