Agent multiplexer · a binary, not an app Run all your coding agents from one terminal, on any box, even over ssh. Each runs in its own real terminal, on a server that keeps it alive when you close the laptop. See blocked, working, and done at a glance, and reattach from your phone.

# why herdr Run agents where the work is. Attach from anywhere. Agents run wherever the work is: a server, a Mac Mini, a sandbox VM, anywhere you can ssh. You attach from any terminal, even a phone. Desktop agent managers can't leave the machine with the GUI.
