Your agents keep working when you step away from the desk. dev-mux shows you what they're doing โ and lets you answer them from anywhere. dev-mux is a cockpit for the terminal sessions running on your own machines: AI coding agents, builds, test runners, deploys, service logs. It connects to a hub you run yourself, so your code and your machines stay yours. THE FLEET AT A GLANCE See every machine and every session in one view. Live status tells you what's running, what finished, and โ the one that matters โ what is sitting blocked waiting for you. ANSWER WITHOUT SITTING DOWN When an agent stops to ask "apply this patch?", dev-mux tells you. Approve or decline straight from the notification, or open the session and answer in full. The thing that used to cost you a round trip to the desk now costs a tap. VOICE, ON DEVICE Talk to a session instead of typing at it. Tap the Talk button, say what you want, watch the words appear as you speak, tap again, and dev-mux sends it. Recognition runs entirely on your iPhone using Apple's on-device speech engine โ your voice is never uploaded, not to dev-mux, not to your hub, not to anyone. The microphone can be opened between the tap that starts it and the tap that stops it. LIVE ACTIVITIES Pin a session to your Lock Screen and Dynamic Island. Watch a long build or a working agent without unlocking your phone. FILES Browse, read, and edit files on your machines. Fix the typo you spotted in the log without opening a laptop. A REAL TERMINAL WHEN YOU NEED ONE For the times a cockpit isn't enough, dev-mux includes a full terminal for the machines you already have access to โ proper PTY, real keyboard, host-key verification that refuses a changed key. BUILT TO BE YOURS * No account. No sign-up. No email address. You point the app at your hub and that's the whole setup. * No analytics, no trackers, no advertising, no third-party SDKs collecting anything. * Your credentials live in the iOS Keychain, on this device only. * Everything talks to your hub and nothing else. dev-mux requires a hub to connect to your own machines. Setup instructions at dev-mux.com.
