Liveblocks

Liveblocks is a set of real-time collaboration APIs and pre-built components that let developers add Figma-like multiplayer features—presence indicators, live cursors, comments, and co-editing—to any web application. It works with React, Vue, and vanilla JavaScript and handles all the complex collaborative state management behind the scenes. Liveblocks is used by teams building design tools, productivity apps, and collaborative SaaS products.
