electric-sql/electric is a read-path sync engine for Postgres that solves real-time data sync challenges including partial replication, fan-out, and data delivery. It integrates with CDNs for scalable data distribution so teams do not need to build their own sync infrastructure.
Project overview
By focusing specifically on the read-path sync problem for Postgres and managing partial replication through Shapes, this project addresses the complex fan-out and delivery difficulties that teams face when synchronizing database subsets to applications without maintaining custom sync code.

Best for
Developers who need to sync subsets of Postgres data to applications and want CDN-integrated delivery without building custom sync infrastructure.
Key capabilities
Manages partial replication using Shapes to sync subsets of Postgres data.
Includes an optional Phoenix LiveDashboard for real-time monitoring of the running system. The dashboard endpoint is completely unauthenticated: anyone with network access to the port can view internal system state.
Limitations and risks
The optional Phoenix LiveDashboard endpoint is completely unauthenticated. Anyone with network access to the port can view internal system state. Restrict network access to the dashboard port before deployment.
Getting started
A Postgres database with logical replication enabled must be available. Coding is optional for use.
