SyncedStore is a TypeScript library providing an easy-to-use reactive API on top of Yjs CRDTs for building real-time collaborative web applications. It lets developers work with plain JavaScript objects that sync automatically across users and devices, with offline support and conflict resolution built in.

Use cases

• build a multiplayer todo app that syncs across devices
• add real-time collaboration to a React app
• build an offline-first app that syncs when back online
• collaborative text editing with rich text
• sync shared state between multiple users without a backend conflict logic
• build a collaborative whiteboard or document editor

When to choose

• you want CRDT-based collaboration with a simple object-oriented API instead of Yjs's lower-level types
• you use React, Vue, or Svelte and want reactive bindings
• you need offline-first sync with automatic conflict resolution
• you want to build local-first, decentralized apps

When to avoid

• you need a mature, battle-tested solution with a large ecosystem and frequent updates
• you only need simple server-authoritative state sync without offline support
• you need non-JavaScript platforms
• your data model doesn't fit CRDT semantics like counters or strict transactional consistency
