bitchat

bitchat is a decentralised peer-to-peer messaging app with a dual transport design: local Bluetooth mesh networks for offline communication, and the internet-based Nostr protocol for global reach. There are no accounts, no phone numbers and no central servers. Private messages are end-to-end encrypted, with automatic multi-hop relay over Bluetooth LE and a familiar IRC-style command set. It was vibe-coded over a weekend by Jack Dorsey using Block's Goose agent.
