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 14 more developer resources.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/electric-sql: open an issue to ask a question, or submit a pull request to add artifacts.
