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

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.
