What is this?
Herdr is a terminal runtime that coding agents like Claude Code, Codex, Cursor, OpenCode, and Grok live on — it is a background server/multiplexer that keeps their terminal sessions running even after you close the client or lose your SSH connection, while organizing multiple agents into panes you can monitor at a glance.

Yes, herdr has a plugin system for extending panes and workflows, and plugins can be browsed through its marketplace.Is herdr keyboard-only like tmux, or can I use the mouse too?Both — herdr supports tmux-style prefix-key shortcuts alongside first-class mouse click, drag, and split, so you can switch between them depending on the moment.
