Rethinking Apps with Local-First Architecture
summary
Shows a concrete local-first stack: the Ditto SDK creates a self-organizing mesh with a “rainbow” multitransport connection (Wi‑Fi, Bluetooth, cellular, multihop), syncs deltas only, and uses CRDTs for automatic merges plus mutually authenticated TLS 1.3 for security. Claims a production Airbus A350 deployment that works inside a Faraday-like fuselage and an airline case that saves $500,000 per year on printing. Includes an ATAC edge‑sync plugin example for offline emergency team awareness.
