What is Electric SQL?
Electric SQL provides composable sync primitives that enable real-time data synchronization for applications built on existing technology stacks, particularly those using PostgreSQL. It allows developers to create highly reactive and collaborative applications by handling partial replication, data delivery, and fan-out from PostgreSQL databases. The platform offers solutions like Postgres Sync for read-path synchronization, Durable Streams for resilient AI applications, and TanStack DB for a reactive client-side data store with instant local writes.
Electric SQL is designed for developers looking to add real-time, collaborative features to their applications without overhauling their current infrastructure. It integrates with popular frameworks and platforms like Next.js, React, Phoenix, AWS, and Cloudflare. The product aims to simplify the development of complex real-time functionalities by providing a robust sync engine and client-side tools, allowing for offline-first capabilities and sub-millisecond reactivity. It also offers Electric Cloud for scalable, turnkey hosting of its sync and streaming services.

Electric SQL FAQ
How does Electric SQL facilitate real-time data synchronization with existing Postgres databases?
Electric SQL offers a Postgres Sync engine that handles partial replication, data delivery, and fan-out from your existing Postgres database. This allows for real-time sync without requiring significant changes to your current stack or imposing new technology choices.
What is the primary function of 'Shapes' within the ElectricSQL system?
Shapes are the core primitive for controlling data synchronization in the ElectricSQL system. They define what data is replicated and how it is synchronized across different clients and the database.
Can Electric SQL be used to embed a full database directly within a client or runtime environment?
Yes, Electric SQL provides PGlite, an embeddable Postgres solution with reactivity and sync capabilities. This allows for a full database to operate directly inside your client or runtime.
What is the purpose of Durable Streams in the Electric SQL ecosystem?
Durable Streams are persistent, addressable, real-time streams designed to power resilient and collaborative AI applications. They provide a robust mechanism for handling continuous data flow in multi-agent systems.
Which client-side library does Electric SQL integrate with for reactive application development and instant local writes?
Electric SQL integrates with TanStack DB, a reactive client store. This integration enables sub-millisecond reactivity and instant local writes for building high-performance applications.
How does Electric SQL support authentication and authorization for synchronized data?
Electric SQL provides a dedicated guide on how to implement authentication and authorization. This ensures secure access and control over the synchronized data within your applications.
