AI-Generated Review

What is gmux?

gmux delivers a polished tmux setup inside the Ghostty terminal, tailored for agentic coding workflows like gstack's plan-review-ship cycle. It visualizes AI agent activity (Claude Code or Codex sessions) with tab indicators, tracks live dev server ports in window status, and colors git worktrees for quick spotting. Shell scripts handle pane borders showing working directories, plus a Docker sandbox for safe testing—symlink the configs or run `docker run -it --rm gmux-test` to spin it up.

Why is it gaining traction?

It skips tmux prefix hell with Ghostty's Cmd+1/2/3 for window switching and Opt+Cmd reordering on MacBooks, plus Hyper+M zoom. Agent "working" spinners and port dots (⏺) give instant feedback during AI tasks or local servers, standing out from vanilla tmux. Two flavors—opinionated C-Space prefix or stock C-b—make it approachable for gmux mac users tweaking terminal github clone sessions.

Who should use this?

AI workflow devs pairing tmux with gstack or Claude on gmux macbook pro setups, especially those juggling multiple dev servers and agent panes. Suited for gmux programmers debugging "gmux not active" issues or needing live port watchers during terminal github authentication flows.

Verdict

With 17 stars and 1.0% credibility score, gmux is early-stage but battle-tested via Docker—docs cover quick starts and keybindings clearly. Test the sandbox before committing; solid for Ghostty fans, skip if you're iTerm-bound or prefix-agnostic.
