Sync with any Backend
RxDB’s high-performance replication protocol powers real-time synchronization between clients and servers. While specialized plugins exist for GraphQL, CouchDB, P2P, Firestore, and NATS, it remains backend-agnostic — seamlessly integrating with any infrastructure over HTTP for unmatched flexibility and speed.
Online is Optional
RxDB adopts an offline-first approach, keeping your app fully functional even without a connection. Data is stored locally on the client and seamlessly replicated in the background, and you can even skip the backend entirely if you choose.
- Keep your app running offline
- Boost perceived performance
- Simplify and speed up development
- Reduces backend load and scales better
