About PowerSync
PowerSync is a sync engine that keeps a local SQLite database for every user or agent in sync with your backend database. It targets web, mobile, desktop, and embedded apps, syncing Postgres, MongoDB, MySQL, SQL Server, and Azure DocumentDB (alpha) to deliver real-time, offline-capable data.
Key Features
When teams evaluate it, the core value is tying client-side data to an existing backend in a way that keeps UI responsive under unreliable networks and supports bi-directional updates:
Backend Integration
Connects your backend databases (Postgres, MongoDB, Azure DocumentDB, MySQL, SQL Server) to the PowerSyncService, enabling scalable partial syncing and a single source of truth for clients.
Client-side Persistence
Uses SQLite on every client to store data locally with real-time streaming updates and consistency guarantees, so apps feel instant.
Bi-directional Sync & State Transfer
Manages two-way data flow between server and client, transferring state automatically and reducing manual conflict handling.
Cross-Platform SDKs
Offers client SDKs across JavaScript, React Native, Vue, Electron, Capacitor, Tauri, Svelte, Next.js, Nuxt, and more (plus Flutter, React Native Expo, Kotlin Multiplatform, Swift, Node, .NET, Rust) for web, mobile, and desktop.
Summary
Best for product teams building offline-first apps, field operations data collection, and real-time dashboards.
