Herdr: One terminal for he whole herd

Herdr, a new terminal-based agent multiplexer, launches to let developers run and manage multiple coding agents from a single terminal session that persists across disconnects and remote SSH connections. The tool, available as a binary for Linux, macOS, and Windows, offers agent-aware panes, tabs, and a JSON API, positioning itself as a lightweight alternative to tmux and desktop agent apps.

Your machine Split panes, create tabs, and keep agents running while your terminal comes and goes. bash $ herdr 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.
