PowerSync is a service and set of client SDKs that keeps backend databases in sync with on-device embedded SQLite databases.

It lets you avoid the complexities of using APIs to move app state over the network, and enables real-time reactive local-first & offline-first apps that remain available even when network connectivity is poor or non-existent.
