the runtime your coding agents live on.

• always running — herdr is a background server; the terminals live inside it. close the lid, drop the network, or restart the machine; agents keep working and sessions come back. reattach from any terminal, or over ssh.
• never hunt for the stuck one — every pane is marked working, blocked, or idle. when an agent stops and needs an answer, herdr says so.
• agent-native — agents drive herdr through the cli and socket api: they can spawn panes, prompt each other, and wait until another agent is genuinely blocked. agent skill →
• runs what you already run — claude code, codex, cursor, opencode, grok and the rest. herdr doesn't wrap or replace them; it owns their terminals.
• keyboard and mouse, both first-class — tmux-style prefix keys and click, drag, split. pick per moment, not per tool.
• plugins — extend panes and workflows. browse the marketplace →
• one rust binary, no electron — runs in whatever terminal you already use.
