herdr

About

herdr is a background terminal server built for the specific failure modes of long-running coding agents: a closed laptop, a dropped SSH connection, or a machine reboot used to kill a session mid-task. A daemon owns the terminal sessions that agents such as Claude Code, Codex, Cursor, and OpenCode run in, so those sessions persist across disconnects and reboots and can be reattached from any terminal or over SSH. Each pane reports working, blocked, or idle status so a developer can see at a glance which agent needs input, and a socket API lets agents themselves spawn panes, prompt each other, and wait on blocked peers. The interface keeps tmux conventions (prefix keys) while adding mouse-driven splits, and a plugin system with a marketplace extends the runtime. It ships as a single Rust binary with no Electron, with Windows support in beta.
