We have checked the project site of cmux 154 times since 15 Sept 2026, and the site answered every time. The site's visible text last changed on 12 Oct 2026.

What it does

A native macOS terminal built on Ghostty and aimed at running coding agents. It has vertical tabs showing git branch, working directory and ports, notification rings that light up a pane when an agent needs attention, split panes, an in-app browser and a CLI for scripting it. It works with Claude Code, Codex, OpenCode, Gemini CLI, Kiro and Aider.

Evidence

Each bar is one request to the project's own site

This one is installed and run on your own machine, so what we re-check is the project’s site — whether it is still published and still reachable. We cannot tell you from here that the tool itself runs.
