herdr
About herdr
herdr is a terminal-based agent multiplexer designed to manage multiple coding agents within a single terminal session. It provides each agent with its own real terminal view, allowing full-screen terminal user interfaces to render correctly. The tool organizes agents into workspaces with tabs and panes, offering visual indicators for agent states such as blocked, working, done, or idle.
herdr operates as a lightweight Rust binary that runs on Linux, macOS, and Windows (beta), with no dependencies or GUI requirements. It supports persistent sessions that remain active even when detached, enabling reattachment from other terminals or devices via SSH. The tool includes a socket API for scripting and integration with various coding agents.
