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.
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:
- A fallback that read the
sessionKeycookie 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 toapi.claude.ai. - 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.
git clone https://github.com/babakarto/CodexBar-Win.git
cd CodexBar-Win
pip install -r requirements.txt
python codexbar.pyOr double-click CodexBar.bat — it installs dependencies and launches.
- Windows 10 or 11
- Claude Code CLI installed and logged in (
claudein PATH) - Python 3.10+
- Dual provider — Claude Code + OpenAI Codex tabs with smooth animated transitions
- Live usage bars — session and weekly limits with color-coded percentages
- Reset countdowns — know exactly when your limits refresh
- Cost tracking — today's spend and 30-day totals from local logs
- Native popup — customtkinter window with rounded corners, slide-up animation
- Provider branding — Claude orange palette + OpenAI dark/green theme, tray icon switches per tab
- Smart default tab — opens on Codex (with the OpenAI tray icon) when Claude Code is not installed
- Auto-refresh — updates every 5 minutes
- Zero config — reads everything Claude Code already stores locally
CodexBar tries multiple methods in order, using the first that succeeds:
| Priority | Method | What it does |
|---|---|---|
| 1 | CLI (PTY) | Spawns interactive claude via pseudo-terminal, sends /usage, parses output |
| 2 | OAuth token | Reads ~/.claude/.credentials.json, calls Claude.ai API |
| 3 | JSONL logs | Scans ~/.claude/projects/ for conversation logs (always runs for cost data) |
| CodexBar (macOS) | CodexBar-Win (Windows) | |
|---|---|---|
| UI | SwiftUI menu bar popup | customtkinter system tray popup |
| Language | Swift | Python |
| Providers | 16+ (Claude, Cursor, Copilot, Gemini...) | Claude Code + OpenAI Codex |
| Data source | CLI PTY | CLI PTY → OAuth → JSONL |
| Install | brew install --cask steipete/tap/codexbar |
Run from source (pip install -r requirements.txt) |
| Auto-update | Sparkle framework | git pull |
| Browser access | Keychain cookie read | None |
| Size | ~5 MB (native) | ~80 KB of Python (plus deps) |
| License | MIT | MIT |
| Problem | Fix |
|---|---|
| No usage data shown | Make sure claude is in PATH and you're logged in |
| "winpty not found" | pip install pywinpty |
| Popup doesn't appear | Check the system tray overflow area (click ^ arrow near clock) |
| CLI shows 0% | Another Claude Code session may be running — CodexBar spawns its own PTY |
Windows port inspired by steipete/CodexBar (MIT) by Peter Steinberger — the original macOS menu bar app.
