CodexBar Win

CodexBar for Windows
System tray app that shows your real Claude Code & OpenAI Codex usage — session limits, weekly limits, reset times, and API costs — right from the Windows taskbar.

Windows port of steipete/CodexBar for macOS.

Security note (please read)

Releases v1.0.0 – v1.1.2 shipped a PyInstaller CodexBar.exe that antivirus engines
flag as a trojan/infostealer. Those binaries have been removed and are no longer
available. The detection was triggered by two things:

1. A fallback that read the sessionKey cookie from Chrome/Edge/Brave (copying the
   cookie database and decrypting it with DPAPI + AES-GCM) to call the Claude.ai usage
   API. That is the exact technique used by real infostealers, and AV heuristics cannot
   tell the difference — even though the cookie was only ever sent to api.claude.ai.
2. An unsigned, single-file PyInstaller executable, which is a common false-positive source
   on its own.

Nothing was ever exfiltrated, but shipping browser-cookie-decryption code was the wrong
design. As of this commit the app never touches your browser: it only uses the
Claude Code CLI and the credentials file Claude Code already stores locally.
No prebuilt executables are distributed anymore — run it from source so you can read
exactly what it does.

If you downloaded an old CodexBar.exe, delete it. There is nothing else to clean up.
