Quick answer
CodexBar has no official Windows build as of October 2026. Its README points Windows users to two community projects, Win-CodexBar and CodexBar-for-Windows. UsageAtlas is another option, a free, open-source Windows app for Codex, Claude Code, Cursor, and 11 more tools.
Your options on Windows
- Win-CodexBar. A community port built with Tauri. It is not code-signed, and it installs with
winget install Finesssee.Win-CodexBar. - CodexBar-for-Windows. A community project that relies on WSL2.
- UsageAtlas. A native Windows app with an installer. It shows Codex and Claude limits in the tray, keeps history, and sends alerts.
What UsageAtlas shows for Codex
UsageAtlas reads the Codex CLI you already signed in to. You see the five-hour and weekly windows with reset times, your credit balance, and tokens by day, model, and project. Claude Code and Cursor sit on the same screen.
CodexBar covers far more providers. If you rely on one that UsageAtlas does not read, a port may suit you better.
Install it on Windows
- Download the Windows installer from the download section.
- Run it. SmartScreen asks first because the build is not code-signed yet, so choose More info, then Run anyway.
- Make sure the Codex CLI is signed in with your ChatGPT account.
- Open UsageAtlas. Codex shows up with both windows.
