What is codexu?

codexU is a macOS menu bar and desktop application built to help developers monitor their OpenAI Codex and Claude Code usage in one place. It shows how much of your usage quota you have left, when it resets, how many tokens you have used today, and what tasks are currently active, all without needing to open a browser or terminal. The app is aimed at people who use OpenAI Codex, Codex CLI, or the Codex desktop app regularly, especially those on ChatGPT Pro or Team plans who want a quick view of their five hour and seven day quota windows. It also supports users who split their work between Codex and Claude Code and want a single window that combines both. Beyond quota tracking, codexU includes a feature the developer calls an AI leadership score. It looks at how many AI agents you have directed over a rolling 28 day period, how long those agents worked, and how well you coordinated multiple agents running at once. The score is calculated using only verifiable local data, such as agent start and stop times and parent child relationships, and everything is processed on your Mac. No usage data, session logs, or account information is uploaded anywhere. The interface includes a color coded usage ring, a menu bar summary, a heat map of token use over the past six months, project rankings, and a list of which tools and skills you have used most. You can resize the main window, choose between several color themes, and set a keyboard shortcut to show or hide it. codexU requires macOS 13 or later and a working Codex installation that has been used at least once. Claude Code tracking is optional and reads local transcript files if you choose to enable it. It is distributed as a downloadable DMG file from GitHub Releases rather than the Mac App Store, so the first time you open it you need to manually approve it in System Settings. Building from source requires the Xcode Command Line Tools.
