- People seeking private, serverless messaging
- Worth noticing
- The homepage says there is no searchable user directory; contact exchange uses rotating QR codes, one-time invite files, or Android NFC.
Field notes
The listed contact methods are designed to avoid searchable identities: a QR code rotates every minute, invite files are single-use, and Android phones can link by NFC. The page names ML-KEM-768 + X25519 and RFC 9420 MLS, but also labels the project closed source and asks users to verify download checksums. macOS, iPhone, and radio-based mesh mode are presented as future additions.
