Herdr, on your phone.

Your chosen relaySetup & coordinationEncrypted WebSockets
Once WebRTC connects, screens, history and input travel directly between your devices. The relay stays connected for pairing, encrypted signaling, revocation and push.
If the direct connection is blocked or drops, encrypted terminal traffic uses the relay. Shellbell retries WebRTC while you’re using the app.
Your terminal content stays encrypted on both routes. Transport details
