Overview
PowerSync is a Flutter/Dart SDK that enables real-time synchronization between local SQLite databases and remote cloud databases such as Postgres, MongoDB, MySQL, or SQL Server. It allows developers to build offline-first applications with seamless data sync across devices and platforms. The SDK handles conflict resolution, data consistency, and background synchronization automatically, reducing the complexity of managing state in distributed apps. With support for Android, iOS, Web, macOS, Windows, and Linux, PowerSync ensures cross-platform consistency and reliability.
