hrdx is a new, experimental terminal multiplexer designed for the AI agent era. It offers a minimal and lightweight interface where each project gets its own workspace, complete with tabs and real terminal panes. Users can run agent CLIs like Codex, Claude, pi, or zot side by side with plain shells, all within a single view.

The sidebar displays workspaces, Git branches, and tabs, while each pane has a status circle that animates when an agent is busy and turns orange when finished. hrdx ensures full terminal compatibility by using genuine PTY sessions and supporting features like scrollback, mouse selection, drag-to-resize splits, and keyboard protocols. It also provides a JSON socket API for scripting and editor integration, allowing external tools to inspect and control panes. Installation is simple via a curl command, and it runs on macOS, Linux, and Windows (10 1809+).

Configuration is user-friendly, with a settings window for toggling agents, notification sounds, and color themes, all persisted as JSON. hrdx aims to streamline multi-agent workflows by keeping everything visible and accessible, making it a practical tool for developers who juggle multiple AI assistants.
