Electric

Electric is a local-first sync framework for mobile and web applications. Local-first is a development paradigm where your application code talks directly to an embedded local database and data syncs in the background via an active-active database replication to the central database. With Electric, you have SQLite as the local embedded option and PostgreSQL for the central store. Although local-first greatly improves user experience, it is not without challenges, and the inventors of CRDT have worked on the Electric framework to ease the pain.
