bitchat-tui

bitchat-tui is a terminal-based secure messaging client implementing the BitChat protocol for off-grid, peer-to-peer communication over Bluetooth Low Energy (BLE).

The main feature of this TUI client is that it does not need an internet connection to work, only Bluetooth and a bluetooth peer server. It supports encryption, Bluetooth mesh networking, public and private channels, direct messaging, no account registration, password-protected channels, user blocking and ownership transfers.
