Knit is an offline, serverless, end-to-end-encrypted mesh messenger for Android. Phones talk directly over Wi-Fi Aware (NAN) and Bluetooth LE — both radios at once — and relay for each other hop by hop. No internet, no accounts, no servers, no Google Play Services.

This is the first public open-source release (GPL-3.0-or-later).

Highlights

  • Dual-radio mesh relay — Wi-Fi Aware + Bluetooth LE simultaneously behind one MeshTransport seam, no GMS
  • Public "Nearby" broadcast room, 1:1 DMs, and multi-member group chats
  • End-to-end encryption for DMs & groups (Tink HPKE/X25519 + AES-256-GCM + Ed25519), TOFU key pinning, safety-number / QR verification
  • Store-and-forward delay-tolerant delivery with content-digest anti-entropy sync
  • Reactions, @-mentions, and content-addressed image attachments
  • On-device content moderation (toxicity text + NSFW image), fully offline
  • Offline app sharing (on-device split-APK merge & re-sign)
  • Encrypted at rest (SQLCipher)

Requirements

Android 10 (API 29)+ with Wi-Fi Aware and/or Bluetooth LE. A device with only one radio still meshes over it.

See the README for build/run instructions and the full feature list.
