cr-sqlite is a run-time loadable extension for SQLite and libSQL, written in Rust, that adds multi-master replication and CRDT-based conflict-free merging to SQLite databases. It lets independently written offline databases converge when synced, functioning like 'Git for your data' in local-first and collaborative applications.

Use cases

• sync sqlite data between devices
• build offline-first apps with local writes
• implement realtime collaboration without a conflict resolution layer
• merge two sqlite databases that took independent writes
• make apps resilient to network partitions
• build local-first p2p applications with sqlite

When to choose

• your app needs offline editing with automatic conflict-free merging
• you want multi-writer replication on top of SQLite or libSQL
• you're building local-first, collaborative, or P2P software
• you need device-to-device sync without a central server

When to avoid

• you need a traditional single-writer client-server database with strict consistency
• your data model requires server-side validation of every write
• you're not using SQLite and can't adopt it
• you need heavy transactional guarantees across distributed writes
