A decentralized peer-to-peer messaging app that combines offline Bluetooth LE mesh networking with internet-based Nostr protocol transport, requiring no accounts, phone numbers, or central servers. It offers end-to-end encryption via the Noise Protocol, IRC-style commands, location-based geohash channels, and multi-hop message relay across nearby devices.
Use cases
- chat without internet or cell service
- send messages during a disaster or network outage
- message privately without giving a phone number
- run a group chat with no central server
- communicate when the internet is censored or shut down
- find nearby people via location-based chat rooms
- relay messages across multiple hops through peers
When to choose
- you need offline messaging that works purely over Bluetooth mesh
- you want censorship-resistant, serverless communication with E2E encryption
- you prefer IRC-style commands and ephemeral, account-free chat
- you want a native iOS/macOS/Android app with a verifiable public-domain source build
When to avoid
- you need guaranteed message delivery or long-term message history
- you require large file sharing or media-heavy group chats
- you need enterprise features like user management or compliance
- you depend on reliable global delivery when no peers or Nostr relays are reachable
