PTT-Radio brings the walkie-talkie to the web using open-source, peer-to-peer WebRTC. Just hold a key to speak and release to transmit. Zero audio servers, zero telephony, and total privacy—your encrypted voice (Opus/SRTP) travels directly to anyone in the room. Real-time audio, stripped to its core.
