Herdr

Herdr is a free, open-source native app for running AI coding agents such as Claude Code, Codex, Amp and Pi. The agents do not live in the app window: they run in herdr-core, a small server on your machine, so quitting, updating or crashing the app leaves every terminal in place. You give each repository a space and each task a tab, and a sidebar shows which agent is working, done or waiting for you. It is built for developers who run several agents at once, often on more than one computer. Any machine you can reach over SSH, such as a server, VM or cloud sandbox, joins the same sidebar, and iPhone and Android apps let you answer an agent from your phone without an account or a relay server. Agents can start helper agents with the hc command, steer them and get their reports back in their own input. Layouts, keys, themes and mods are plain files with an AGENTS.md, so your agent can change the app for you. One limitation: status depends on the OSC 7501 protocol, so agents that do not report it, or that run inside tmux, show no status. A reboot stops running agents instead of resuming them.
