hrdx terminal multiplexer runs multiple AI agent CLIs side by side with session persistence
hrdx is an experimental Go-based terminal multiplexer built for running AI agent CLIs such as Codex, Claude Code, pi, and zot alongside regular shells, with workspace management, real PTY sessions, and a scriptable socket API.
Engineers juggling multiple AI coding agents across projects get a single window with sidebar workspaces, per-agent status spinners, and terminal sessions that survive restarts. The socket API lets editors and scripts control panes programmatically, and custom agent CLIs can be registered via small JSON files.

hrdx presents projects as workspaces in a sidebar with tabs and split panes, each running a genuine PTY session rather than a wrapper.
Sessions persist across quit and relaunch via a lightweight session holder, and agents resume from their own conversation stores if the session is gone.
A JSON socket API lets external scripts inspect pane states, spawn panes, type into agents, wait for completion, read screens, and subscribe to live events.
