Liveblocks provides ready-made collaboration infrastructure and components to enable real-time multiplayer editing, comments, AI agents, and notifications in web applications for developers and product teams.

---

🚀 Overview

Liveblocks is a collaboration engine that delivers pre-built, customizable features like comments, multiplayer cursors and editing, AI copilots, and notifications, allowing developers to integrate real-time collaboration into their apps with minimal effort.

It solves the challenge of building complex real-time collaboration infrastructure from scratch, which typically requires handling WebSockets, state synchronization (e.g., CRDTs, Yjs), offline support, undo/redo, and scalability—saving months of engineering time. Instead, teams can drop in ready-made React components and hooks.

Built for developers, product teams, and companies creating engaging products like Figma, Notion, or Google Docs. The goal is to help teams ship collaborative experiences faster, boost user engagement, drive adoption with AI features, and unlock revenue through premium collaboration tools.
