Key features include:

  • Bluetooth Low Energy mesh messaging with nearby peer discovery and multi-hop relay
  • No phone number, account, or central server required
  • End-to-end encrypted private messages
  • Nostr support for internet-based reach beyond the local Bluetooth mesh
  • Native iOS, macOS, and Android apps with public source code on GitHub

Use Bitchat when off-grid, local, or censorship-resistant messaging matters more than mainstream convenience. For everyday encrypted messaging with a broader contact base, Signal is still the easier default.

Treat Bitchat as an off-grid and local-resilience tool, not a general Signal replacement. It may be useful when nearby local communication matters more than mainstream reach, but high-risk users should verify current audits, protocol documentation, device exposure risks, and operational-security assumptions before relying on it.
