[⇌] Radix Relay

Hybrid mesh communications when it matters most

Open-source communications system combining internet (Nostr) and local mesh (BLE) transports with Signal Protocol encryption for activists, disaster response, and infrastructure-independent communications.

Radix Relay UI

Features

Hybrid Transport

Automatic failover between internet (Nostr) and local mesh (BLE) networks. Stay connected even when infrastructure fails.

Signal Protocol Encryption

End-to-end encryption with perfect forward secrecy. Your messages remain secure even if keys are compromised.

Cross-Platform

Built with modern C++ and Rust, supporting Linux, Windows, and macOS.

Emergency Focus

Designed for activists, disaster response teams, and anyone who needs reliable communications when traditional infrastructure is unavailable.
