About Liveblocks
What is Liveblocks?
Liveblocks is a developer platform that provides realtime infrastructure for building multiplayer, collaborative applications. It handles concurrent edits on shared data so that multiple users and AI agents can work together without conflicts.
Who is it for?
Liveblocks is designed for engineering, product, and design teams at startups and established companies who want to add collaborative features like co-editing, comments, whiteboards, and AI copilots to their apps without building the underlying sync infrastructure from scratch.
Key use cases
Build document annotations like Google Docs, AI copilots like Notion, multiplayer editing like Figma, whiteboards like Miro, spreadsheet-like collaboration, and contextual commenting. It also supports 3D tools and creative apps.
How it solves the concurrency problem
When people and AI agents work on the same data, concurrency becomes critical. Liveblocks uses CRDTs (Conflict-free Replicated Data Types) for automatic conflict resolution, realtime sync via a global edge network, and offline support. It includes pre-built React components and SDKs for faster development.
Key features
- Multiplayer presence — See online users, live cursors, selections, and avatar stacks in real time.
- Comments & threads — Add contextual conversations, emoji reactions, and resolve threads directly inside your product.
- AI Copilots — Integrate individual AI assistants that collaborate alongside human users.
- Persisted storage — Conflict-free data stored and synced across sessions with no backend to manage.
- Realtime sync engines — Includes both Liveblocks Storage and Yjs (CRDT) for flexible collaboration.
- Offline support & multiplayer undo/redo — Keep working offline; changes sync automatically, each user maintains their own history.
- Pre-built React components — Ready-made UI components for comments, notifications, cursors, and more to speed up development.
