What it does

Herdr is a free, open-source desktop app for running AI coding agents such as Claude Code and Codex side by side. Agents run in real terminals hosted by herdr-core, a small server on your machine, so they keep working when the window is closed or the app updates. A sidebar shows which agent is working, done or waiting on you; agents can start helper agents and get their reports back; and remote machines join over SSH. The app's layout, tabs, keys and themes are plain files your own agent can rewrite on request, and the community gallery lists hundreds of shared layouts and mods.

Features

  • Agent status at a glance. Each agent reports whether it is working, done or waiting on you, and the sidebar and tabs flag the ones that need attention. Spaces map to repos and tabs to tasks. Official source 1 ↗
  • Agents survive closing the app. Agents run in herdr-core rather than the window, so quitting, updating or crashing the app leaves every terminal where it was. Official source 1 ↗
  • Agents that run agents. An agent can hand a review or test run to a helper agent (Claude, Codex or a script), steer it, and receive its report directly in its own input. Official source 1 ↗
  • Remote machines in one sidebar. Servers, VMs and cloud sandboxes reachable over SSH appear in the same sidebar, and their agents keep running while your laptop sleeps. Official source 1 ↗
  • Reshape the app by asking. Layout, sidebar, tabs, keys and themes live as plain files with an AGENTS.md guide, so you describe a change and your coding agent writes it, for example a kanban board of agents. Official source 1 ↗ · Official source 2 ↗
  • Works with any terminal agent. Anything that runs in a terminal works; agents that speak the open OSC 7501 status protocol also report their state. Official source 1 ↗ · Official source 2 ↗
  • Community layouts and mods. A public gallery lists shared layouts and mods that your agent can install with one line. Official source 1 ↗

  • No resume after reboot. If the machine reboots or herdr-core stops, agents stop; panes return as shells but Herdr does not restart or resume the agent's work. Official source 1 ↗
  • Status needs OSC 7501. Agents that don't report through OSC 7501 (including older agent versions or agents inside tmux) still run but show no status. Official source 1 ↗
  • Separate from Herdr TUI. The app and the original Herdr TUI do not share agents; what runs in one does not appear in the other. Official source 1 ↗
  • Anonymous usage report. The desktop app sends one anonymous usage report a day (no terminal content, file names or prompts); it can be turned off in Settings. Official source 1 ↗
