ElectricSQL
Local-first sync between client SQLite/PGlite and central PostgreSQL — build apps that work offline but sync magically online.
James Arthur + Valter Balegas founded. Inspired by "Local-first software" (Ink & Switch). Created Electric protocol for CRDT-style sync between Postgres ↔ client. Pivot 2024 to "Electric Sync" — generic Postgres changefeed sync without CRDT complexity. Competitors: Replicache, PouchDB/CouchDB, Yjs+server.
