# PowerSync Docs

> PowerSync is a sync engine that keeps your backend database in sync with in-app SQLite.

Your app reads and writes directly to this local database, so it responds instantly and stays fully functional without a network connection.

PowerSync is made up of the PowerSync Service and a set of client SDKs. The PowerSync Service replicates data from your backend database, partitions it based on what data each user should receive, and streams real-time updates to clients through the PowerSync client SDK.
