Every AI coding limit, next to your clock.
A free Windows 11 tray app that shows how much of Claude, Codex, Cursor and 13 other subscriptions you've used: session and weekly limits, credits, when they reset, and whether you're on pace.
winget install PowerUserZ.OpenTokenUsage
The top number is your session. The bottom one is your week.
Turn on the taskbar strip (experimental) in Settings and each provider you pick gets a logo and two numbers. Open the panel for the rest.
- Top number
- The session limit, the one that resets every few hours.
- Bottom number
- The weekly limit.
- Color
- Starts in the taskbar's text color and warms up to yellow, orange and red as you use more.
- Logo
- Which provider. Up to 6, in the order you choose.
On every limit
- 34%
Used
How much of the limit is gone.
- in 2h 13m
Resets
When the limit starts over.
- 3% in deficit
Pace
Whether you're ahead of or behind an even pace to the reset.
- in 2d 18h
Runs out
When you'll hit the limit at this rate.
When it speaks up
- 80% and 95% by default
Usage levels
A notification at the levels you pick, once per limit until it resets.
Pace and resets
When you're on pace to run out before a reset, and when a limit you'd nearly used up resets.
Sounds
Windows' default, eight built-in sounds or your own file. Quiet during Do Not Disturb.
One-click fixes
Errors come with the fix: run the login command in a terminal, or open the provider's API key page and Windows' Environment Variables.
Service status
A badge on the card when the provider's status page reports an incident (for providers with a public status page).
Make the taskbar yours
Pick what sits next to the clock in Settings. The taskbar strip is experimental: Windows has no official place for it, so a Windows update may move or hide it.
Tray icon
The app icon, a percent, bars, or one number or logo ring per provider.
- Up to 6
Taskbar strip
Logos with session and weekly numbers inside the taskbar, in your fonts, sizes, colors and order.
The panel
Open it from the tray, the strip or a global shortcut. Pin it above other windows, or turn on Remember position and it opens wherever you drag it.

Your usage stays on your PC
No telemetry
The app sends no analytics. Usage goes from each provider to your PC and nowhere else. Besides the providers you turn on, it contacts only their status pages, and GitHub for updates.

On by default: other apps on your PC can read your usage. Loopback only; browsers are refused.
Proxy
Route provider requests through a SOCKS5 or HTTP proxy, set in a config file.
Updates
Checks for new releases every 6 hours and downloads them. Installs when you click Restart to update.
Open source
MIT licensed. Every line is on GitHub.
Questions
How do I see my Claude Code usage limits on Windows?
Install OpenTokenUsage and stay signed in to Claude Code. The app uses Claude Code's existing login, so there's no API key to set up, and shows your 5-hour session limit and weekly limit next to the clock, with reset times, pace and extra usage.
How do I check my Codex usage limits?
Sign in to Codex as usual. OpenTokenUsage reads that login and shows the 5-hour and weekly limits, the code review limit and credits, and can warn you before you run out.
Is there a CodexBar for Windows?
CodexBar and OpenUsage live in the macOS menu bar. OpenTokenUsage does the same job in the Windows 11 notification area: it's built on OpenUsage, inspired by CodexBar, and made for Windows.
Which AI coding tools does it track?
Claude, Codex, Cursor, GitHub Copilot, Antigravity, Amp, Devin, Factory (Droid), Grok, JetBrains AI Assistant, Kimi Code, Kiro, MiniMax, OpenCode Go, Synthetic and Z.ai. Each one is a plugin, and new ones arrive with app updates.
Can it warn me before I hit a limit?
Yes. It notifies you at the usage levels you pick (80% and 95% by default), when you're on pace to run out before the reset, and when a limit resets, with a sound of your choice.
Does it send my usage or logins anywhere?
No. There's no account and no telemetry. Your logins stay on your PC, and the app talks only to the providers you turn on, their status pages, and GitHub for updates.
Is it free?
Yes. It's free and open source under the MIT license. Install it with winget or the installer from GitHub Releases.
Install it in one line
Paste this into Windows Terminal:
winget install PowerUserZ.OpenTokenUsage
Or download the installer and run it. Either way, the app keeps itself up to date.
