Briar on a Mac
P2P messaging over Tor, Wi-Fi & Bluetooth · Mesh Networking
Briar is a peer-to-peer secure messenger that syncs directly between devices over Tor (online) or Wi-Fi/Bluetooth (off-grid), with no central servers; built for resilience and censorship resistance. Primarily mobile, with Briar Desktop and a briar-headless daemon (REST/WebSocket API) for Linux. Pairs with the off-grid radio meshes here.
