ElectricSQL

Overview

ElectricSQL syncs Postgres data to client applications in real-time. Instead of fetching data from an API, the data lives locally on the device — queries are instant, the app works offline, and changes sync automatically when connectivity returns. Think "Postgres replication to the browser." Define shapes (subsets of your data) and Electric keeps them in sync.

When to Use

• Apps that must work offline (field service, mobile, travel)
• Real-time collaborative features (shared lists, dashboards)
• Low-latency reads — querying local data is instant
• Reducing API calls — data is already on the client
• Multi-device sync (phone, tablet, desktop see same data)
