About
PowerSync is a sync engine that connects backend databases (Postgres, MySQL, MongoDB, SQL Server) to in-app SQLite on the client side, enabling real-time, offline-first applications. It handles state transfer, partial data syncing, and bi-directional sync so developers don't need to manually manage network calls, caching, or optimistic updates. The platform consists of a hosted sync service and open-source client SDKs for popular frameworks.
Problem
Developers waste significant time managing network state, cache invalidation, and data syncing between backend databases and client apps.
For
Mobile and web app developers building offline-first or real-time applications
How it works
PowerSync connects to your backend database via a service that replicates changes and streams them to client SDKs, which maintain a local SQLite database and queue writes for upload to your backend API.
