herdr is a terminal multiplexer made for running AI coding agents. Point dotMux at a host running it and its workspaces open as native tabs and panes, with each agent's state marked on its pane.
Free for one host · iOS 26+ · herdr 0.9.0+

Five agents on one box is easy to start and hard to watch from a phone. herdr tracks what each one is doing, and dotMux shows it: blocked, working or done, in a corner of every agent's pane and together in one Agents list. Open the app, see which one stopped for an answer, and go straight there.

Set Multiplexer to herdr when you add or edit a host. dotMux never installs or upgrades herdr on the server, and if it's missing, older than 0.9.0 or won't start, dotMux says which and opens a plain terminal instead. If no herdr server is running, dotMux starts one and leaves it running, since your desktop may share it.
Panes open watching. The first key you type in one takes control of it; a pane someone else controls stays read-only until you choose Take control.

Like mosh, herdr runs its own terminal emulator on the server and sends a redrawn screen. Whatever it leaves off the wire, no client can restore. The form lists these before you save, and the support topic explains each one:
Each live pane streams over its own SSH channel. A server with a low MaxSessions streams fewer panes at once, and the host form tells you how many.
Need images on a host? Choose tmux there instead. The choice is per host, so one server can run herdr while the next stays on tmux.
