## What it is
Liveblocks is a realtime collaboration infrastructure and SDK toolkit for adding multiplayer features, comments, notifications, and AI copilots to web applications. It provides React packages, editor integrations (Tiptap, BlockNote, Lexical, CodeMirror), CRDT-based conflict resolution, and a hosted sync service with a free tier.

## Use cases
- add google-docs-style collaborative editing to my app
- show live cursors and presence for multiplayer editing
- add contextual comments and threads inside my product
- build an in-app notification inbox
- embed an AI copilot chat that acts on shared app state
- sync shared state between users with conflict resolution
- add multiplayer undo/redo to a whiteboard or canvas app
- let AI agents collaborate with users on the same data

## When to choose
- you want ready-made collaboration UI components (comments, notifications, cursors) with minimal backend work
- you need CRDT-based conflict resolution and offline sync without building your own sync engine
- you are building a React/Next.js app and want fast integration with editor frameworks like Tiptap or Lexical
- you want hosted realtime infrastructure with a free tier instead of self-hosting

## When to avoid
- you need a fully self-hosted, open-source realtime backend with no vendor dependency (the service is proprietary with AGPL/Apache dual licensing on parts)
- your app is not web/JavaScript based or you need non-React first-class support
- you only need simple websocket messaging without collaboration features, where a lighter library suffices
- you cannot send user data to a third-party hosted service
