Electric is a read-path sync engine for Postgres that does partial replication [1]. It's agnostic to your choice of client -- you can sync into anything you like. It doesn't handle or mandate a pattern for syncing local writes back to Postgres. Instead, it's designed to allow you to handle concerns like writes and auth using your existing API [2].
Turso Offline Sync is an active-active replication system for distributed SQLite/Turso databases. IIUC, this release adds the capability to sync local writes back to the cloud [3].
