Sync with any Backend

RxDB's easy-to-use Sync Engine powers realtime synchronization between clients and servers. Either use one of our prebuild replication plugins...

OR

...sync with your custom server by implementing only three simple endpoints.

Online is Optional

RxDB adopts the local-first approach by storing data locally on the client and managing continuous synchronization. You can even run your app entirely without a backend.

  • Keep your app running offline
  • Run local queries with zero latency
  • Simplify and speed up development
  • Reduces backend load and scales better
