Local-First Sync, Done Right: Inside the SQLite Sync Stack
TL;DR: Four open-source Python repositories form a complete local-first synchronization stack: sqlite-sync-core captures SQLite changes as structured operations, packages them into self-contained bundles, and applies them deterministically across disconnected devices; sqlite-sync-snapshot adds content-addressed snapshot storage; sync-coordination orchestrates nodes with vector clocks and…
Four open-source Python repositories compose a complete local-first synchronization stack for SQLite databases. sqlite-sync-core handles change capture, operation logs, and deterministic apply. sqlite-sync-snapshot provides content-addressed snapshots. sync-coordination orchestrates nodes with vector clocks and CRDT-style merge. merkle-dag-store serves as the content-addressed block layer.
Together, these packages address offline-first application needs by enabling devices to merge changes without loss, duplication, or corruption, even with schema changes or mid-transfer network drops.
