Liveblocks Collaboration Platform

Liveblocks is a realtime collaboration infrastructure platform that provides the building blocks for adding multiplayer features to web applications, enabling people and AI agents to collaborate on shared data through concurrent editing. Founded by Steven Tey and the Liveblocks team, the platform offers pre-built components for features including document co-editing like Google Docs, multiplayer cursors and presence like Figma, comments and annotations like Notion, inbox notifications like Linear, whiteboard collaboration like Miro, and AI copilots like Microsoft Copilot. The data synchronization engine handles conflict resolution through operational transformation and CRDT algorithms, ensuring that concurrent edits from multiple users merge correctly without data loss or corruption. The Comments component provides threaded discussions anchored to specific content elements, with mentions, reactions, resolved states, and real-time updates. The Notifications system delivers activity feeds through inbox components, email digests, and webhook events. The Presence feature tracks which users are online, their cursor positions, selected elements, and editing focus, with automatic timeout for disconnected users. Liveblocks integrates with React, Vue, Svelte, and vanilla JavaScript through framework-specific packages, and provides a REST API for backend operations. The platform is trusted by engineering teams at companies including Notion, Framer, Pitch, and Spline for their collaborative features.
