Plug-and-play offline-first and real-time data for apps with SQL backends.

PowerSync is an add-on for apps with SQL backends that provides a fully offline-first experience for client applications. It consists of a client SDK and a hosted sync service. PowerSync itself is framework and database agnostic, with initial support for Flutter on the frontend and Postgres on the backend.

Used in conjunction with Supabase, PowerSync enables developers to build offline-first apps that are robust in poor network conditions and that have highly responsive frontends while relying on Supabase for their backend. This guide provides instructions for how to configure PowerSync for use with your Supabase project.
