Hocuspocus is a Yjs CRDT-based WebSocket backend for conflict-free real-time collaboration, written in TypeScript. It provides a server, client provider, and extensions (e.g., SQLite persistence, Redis scaling, webhooks) to add collaborative editing and offline-first sync to apps.

Use cases

• add real-time collaborative editing to my app
• self-host a yjs websocket backend
• sync application state across clients without conflicts
• build an offline-first app that syncs later
• persist yjs documents to a database
• scale collaborative editing across multiple servers with redis
• share cursor and awareness state between users

When to choose

• you use Yjs with editors like Tiptap, ProseMirror, Slate, Quill, or Monaco
• you want a batteries-included, extensible collaboration server with auth hooks and persistence extensions
• you need multiplexing of multiple documents over one WebSocket connection
• you want cross-runtime support (Node.js, Bun, Deno, Cloudflare Workers)

When to avoid

• you need a non-Yjs CRDT or a different sync protocol
• you only need simple polling or REST-based sync without real-time merge
• you rely on other y-providers as your server, since Hocuspocus requires its own provider since v2
