Liveblocks

Liveblocks is infrastructure for realtime collaboration. It syncs shared data between people and AI agents, and it handles conflicts when several users edit the same thing.

Liveblocks keeps application data in sync across users and sessions. Changes are merged automatically using CRDTs, so concurrent edits do not break the app. The platform also includes presence, comments and notifications, so collaborative features can be built with fewer custom pieces.

• Realtime sync for shared application data
• Automatic conflict resolution with CRDTs
• Presence, comments and notifications
• Offline changes synced when reconnected
• Per-user undo and redo in shared rooms

Product teams building collaborative editors, whiteboards or shared tools. Teams adding AI agents that work alongside people on the same data may also use it.

Getting started is free, and paid plans are listed on the pricing page. Data is stored and synced across sessions, and rooms run on a global edge network. Check the pricing page for limits that match your number of users and rooms.
