Real-time Postgres-to-client sync with conflict-free offline support. Sync subsets of data per user with row-level security rules and sub-second replication latency.
Overview
PowerSync is an open-source data synchronization engine that keeps client applications in sync with a PostgreSQL backend in real time, with seamless offline support. Define sync rules to control which rows each user receives, enable optimistic local writes that merge automatically when connectivity is restored, and maintain sub-second end-to-end replication from Postgres through to mobile and web clients. The sync layer supports SQLite on iOS, Android, Flutter, and React Native clients. Row-level security rules enforce per-user data partitioning.
Highlights
- Sub-second Postgres-to-client replication with SQLite offline storage on iOS/Android
- Row-level sync rules -- each user syncs only their authorized data subset
- Conflict-free merge for optimistic local writes across iOS, Android, Flutter, and web

- Amazon ECS
Container image
Containers are lightweight, portable execution environments that wrap server application software in a filesystem that includes everything it needs to run. Container applications run on supported container runtimes and orchestration services, such as Amazon Elastic Container Service (Amazon ECS) or Amazon Elastic Kubernetes Service (Amazon EKS). Both eliminate the need for you to install and operate your own container orchestration software by managing and scheduling containers on a scalable cluster of virtual machines.
Version release notes
Initial container release v1.0.0.
