<p>Deploy Herdr, the terminal runtime coding agents run in, with Claude Code, Codex, OpenCode, Grok Build, Kilo Code CLI, and Cursor Agent CLI already installed. SSH in, run <code>herdr</code>, and start an agent in a pane. You do not install those CLIs yourself.</p>
<h2 id="what-is-herdr">What is Herdr?</h2>
<p>Herdr is a terminal multiplexer for coding agents. Each agent keeps its own pane. You can detach, close the laptop, or drop the SSH session, and the agents keep working. Reattach later with <code>herdr</code>.</p>
<p>This image installs Herdr as a systemd service and preinstalls six agent CLIs Herdr already knows how to run:</p>

<p>Herdr integrations for those agents are installed too, so Herdr can restore their sessions after the server restarts.</p>

<ul>
<li>Herdr server starts on boot and survives SSH disconnects</li>
<li>Six coding-agent CLIs on <code>PATH</code> from the first login</li>
<li>Session-restore integrations for Claude Code, Codex, OpenCode, Grok Build, Kilo Code, and Cursor Agent CLI</li>
<li>SSH only — there is no web interface</li>
<li>Helper scripts to start, stop, restart, and update Herdr and the agents</li>
</ul>
<h2 id="system-requirements">System Requirements</h2>
<p>The agents do most of their work at the model provider. The Droplet needs enough memory to run Herdr plus one or more agent processes.</p>
