Quick answer
UsageAtlas for macOS is a signed and notarized app that sits in the menu bar and opens a full dashboard. It shows Claude Code and Codex limits, reset times, tokens, and history, plus Cursor, OpenCode, Copilot, and more. It is free and open source.
Install on a Mac
Download the .dmg from the download section and drag UsageAtlas into Applications. Apple notarizes the build, so it opens without a security workaround. Updates install in the background.
The same app on your other machines
If you also code on Windows or Linux, UsageAtlas runs there too. That matters if you liked CodexBar on your Mac and want the same view on a work PC.
Questions, answered
Does UsageAtlas run on Apple Silicon?
Yes. The macOS build runs on Apple Silicon and Intel Macs.
Does it need Claude or Codex API keys?
No. It reuses the Claude Code and Codex sign-ins already on your Mac. Some credit-based tools need a key in Settings.
Is the Mac app free?
Yes. It is free and open source under the MIT license.
