Your agents keep working when you step away from the desk. dev-mux shows you what they're doing — 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 — the one that matters — what is sitting blocked waiting for you. ANSWER FROM ANYWHERE When an agent stops to ask "apply this patch?", 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 — 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. 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 — 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.
