Liveblocks
Realtime collaboration infrastructure with embeddable AI copilots for any app.
About
Liveblocks is a developer-first realtime collaboration engine that lets teams drop multiplayer features into web apps without running WebSocket infrastructure. It provides pre-built, customizable components for presence, comments, notifications, and multiplayer editing on top of CRDT-backed storage, with React and JavaScript SDKs.
With Liveblocks 3.0, the platform added embedded AI copilots: context-aware in-app AI agents that chat, take actions, and collaborate alongside users, with AI participation visible through live cursors. An MCP server integration lets AI agents manage collaborative workspaces programmatically, positioning Liveblocks as infrastructure for human-plus-AI realtime experiences.
