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 is a current TanStack partner, and we think they are a strong option for teams building in this part of the 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.
