Install it with:

```bash
curl -fsSL https://herdr.dev/install.sh | sh
```

A tmux-for-agents: real terminal panes over persistent PTY sessions that live on the server, so you detach and reattach from any machine — laptop, another box over SSH, or your phone. Sessions survive disconnects, and per-agent state (blocked, working, done, idle) is visible at a glance.

Controllable from the CLI or a JSON socket API, with 150+ community plugins. No Electron, no accounts, no telemetry. Also available via Homebrew and Nix; Windows install is in beta.
