Electric BETA
Sync little subsets of your Postgres data into local apps and services.
Electric sync engine
The Electric sync engine syncs little subsets of data out of Postgres into local apps and services — wherever you need the data.
You can sync data into:
- web and mobile apps, replacing data fetching with data sync
- edge workers and services, for example maintaining a low-latency edge data cache
- local AI systems, for example running RAG using pgvector
- dev and test environments, for example syncing data into an embedded PGlite database
How does it work?
The Electric sync engine is an Elixir application, developed at packages/sync-service.
It connects to your Postgres using a DATABASE_URL, consumes the logical replication stream and fans out data into Shapes, which Clients then consume and sync.
This enables a massive number of clients to query and get real-time updates to subsets of the database. In this way, Electric turns Postgres into a real-time database.
