ElectricSQL

ElectricSQL is a Postgres sync engine designed to solve the complex challenges of data synchronization, enabling you to build fast, modern, and real-time applications. It acts as the magic ingredient for software that requires seamless data flow between the cloud and local devices, without you having to build a custom sync solution from scratch.

It handles the hard problems of sync for you, including:

• Conflict resolution to merge concurrent writes correctly.
• Referential integrity to maintain data relationships across systems.
• Partial replication to sync only the data a user needs.
• Fan-out for high-throughput data delivery.

Built to work with your existing stack, ElectricSQL integrates with any framework or language that can connect to Postgres. This allows for incremental adoption into both new and established applications. It is architected to scale efficiently, capable of supporting millions of concurrent users from a single commodity Postgres instance. As a fully open-source project, it offers a transparent and robust foundation for your real-time data needs.
