Herdr, a terminal multiplexer built for coding agents, trends on GitHub

Summary: Herdr is a single Rust binary (about 10MB, Linux and macOS, Windows in beta) that runs multiple coding agents in one terminal, each in its own real terminal so full-screen TUIs render correctly, and rolls each agent up to a blocked, working, done, or idle state in a sidebar without hooks. A background server keeps panes and agents alive across detach and reattach over ssh, and a local socket API and CLI let agents drive it. The project describes itself as tmux rebuilt for agents, with no GUI, account, or telemetry. It carries about 10.9k stars with a latest tag of v0.7.1 and reached the GitHub trending list on 2026-07-04.
Why it matters: Managing many concurrent coding agents is an emerging workflow problem, and a terminal-native, ssh-persistent multiplexer targets it without the Electron or macOS-only wrappers of existing GUI agent managers.
