Liveblocks

Overview Liveblocks provides realtime infrastructure for building multiplayer apps and AI agents. It handles concurrent edits on shared data so people and AI can collaborate without breaking the application. Developers use Liveblocks to add collaborative features like live cursors, comments, notifications, and AI copilots to their products. It replaces the need to build custom realtime sync, conflict resolution, and data persistence from scratch. Key Benefits Conflict resolution powered by CRDTs merges concurrent edits automatically without data loss. Global edge network keeps realtime rooms close to users for low latency everywhere. Offline support lets users keep working and syncs changes automatically when reconnected. Multiplayer undo/redo maintains each user's own history even in shared environments. Pre-built React components and SDKs let teams ship collaborative features without months of engineering work. AI copilots help onboard users faster and shorten time to value. How It Works You create a Liveblocks project and install the SDK into your app. You define rooms for shared data, then use the React hooks or REST API to sync presence, storage, and comments across users and AI agents. Liveblocks handles conflict resolution with CRDTs, manages the global edge network, and persists data across sessions — no backend to manage. Use Cases Product teams building multiplayer text editors like Google Docs with realtime co-editing and annotations. Design tool developers adding multiplayer cursors, selections, and comments similar to Figma or Spline. Whiteboard and Miro-like app creators syncing canvas data across users with offline support. Spreadsheet and dashboard builders needing conflict-free data merging for concurrent edits. AI product teams embedding AI copilots that can read, write, and comment on shared data alongside human users. Sales and people platform teams adding contextual commenting and notification inboxes to their SaaS products. Why Choose This Product Liveblocks is best suited for product teams shipping collaborative features who want to avoid building realtime infrastructure from scratch. It works for startups prototyping with the free tier and scales to enterprises needing multi-region hosting, SCIM, and dedicated support. The free tier is limited to 10 projects and 20 simultaneous connections per room, with usage-based pricing for higher scale.
