Show HN: Yet another minimal and lightweight terminal multiplexer written in Go.
hrdx is a new, lightweight terminal multiplexer written in Go, specifically designed for the 'agent era' of software development. It allows users to manage multiple project workspaces and run various AI agent CLIs side-by-side in a single terminal interface.
Why it matters
As developers increasingly rely on multiple AI coding agents, specialized terminal tools are needed to manage these concurrent processes efficiently.
hrdx is a experimental, minimal and lightweight terminal multiplexer built for the agent era: your projects as workspaces in a sidebar, tabs per workspace, and real terminal panes running Codex CLI , Claude Code , pi , zot or plain shells side by side. Kick off an agent in one project, switch to the next, and let the sidebar spinners tell you who is still working.
The article is a technical showcase of a developer utility tool.
