ElectricSQL

ElectricSQL (Electric) is a local-first sync engine for Postgres that streams live database changes to embedded clients in browsers, apps, and AI agents via an HTTP-based Shape sync protocol. It exposes a low-level HTTP API and TypeScript, Elixir, and other client SDKs that materialize real-time Postgres data into local state with sub-millisecond reactivity. Developers can run Electric self-hosted as a Docker service or use Electric Cloud, a managed offering with pay-as-you-go and subscription plans. The platform also underpins PGlite (an embeddable Postgres under 3 MB) and Durable Streams for reliable agent messaging, making it a broader data-infrastructure toolkit for building collaborative and multi-agent systems.

ElectricSQL publishes 1 API on the APIs.io network: Shape API. Tagged areas include Developer Tools, Database, Sync, Local-First, and Postgres.

The ElectricSQL catalog on APIs.io includes 1 JSON-LD context and 1 Spectral governance ruleset.

ElectricSQL’s developer surface includes documentation, engineering blog, changelog, pricing, and 15 more developer resources.
