Offline-first Sync
Sync engine that keeps backend databases in sync with embedded client-side SQLite for offline-first and realtime applications. Postgres and MongoDB are supported, with MySQL and SQL Server in beta. It is especially relevant for teams building with DB, Query.
PowerSync has supported TanStack previously, and we still think they are worth knowing about if their strengths match your stack.
PowerSync is built for one of the harder app problems: keeping client-side SQLite in sync with backend data for offline-first and realtime behavior.
That makes it relevant for TanStack DB and Query users who care about local-first UX and reactive client state.
