Show HN: ElectricSQL, Postgres to SQLite active-active sync for local-first apps
It’s an open source, local-first sync layer that can be used to build reactive, realtime, offline-capable apps directly on Postgres with two way active-active sync to SQLite (including with WASM in the browser).
Electric comprises a sync layer (built with Elixir) placed in front of your Postgres database and a type safe client that allows you to bidirectionally sync data from your Postgres to local SQLite databases. This sync is CRDT-based, resilient to conflicting edits from multiple nodes at the same time, and works after being offline for extended periods.

We are privileged to be building on their research and delighted to be surfacing so much work in a product you can now try out.
