Replicache is a client-side sync framework for building realtime, offline-capable web applications on top of any backend stack. It provides optimistic mutations, realtime subscriptions, and automatic synchronization between browser-local data and a server.

Use cases

• build realtime collaborative apps like shared todo lists or whiteboards
• add offline support to a web app with automatic background sync
• implement optimistic UI updates that roll back when server mutations fail
• sync client state across browsers in a multiplayer app
• add instant local-first data mutations to an existing backend
• build a Figma-like multiplayer experience without rewriting the backend

When to choose

• you need realtime collaboration or offline-first behavior in a web app
• you want to keep your existing backend stack and just add a sync layer
• you want optimistic mutations with automatic rollback on failure

When to avoid

• your app is simple CRUD with no realtime or offline requirements
• you need a fully managed backend sync service rather than a client framework
• you require a permissive open-source license - Replicache uses a custom commercial-friendly-but-proprietary license
