Why this search exists
OpenUsage is a Mac app. It lives in the menu bar and shows how much of each AI subscription you have left. A lot of people find it, then ask the next obvious question: is there an OpenUsage for Windows?
There is not a Windows build of OpenUsage itself. There is Pane. Pane is a from-scratch Windows port of that idea, written for the system tray, MIT licensed, and built so a Windows user gets the same kind of answer without needing a Mac.
What you get on Windows
One tray popover. Claude, Codex, Cursor, Copilot and 17 more providers as cards, not six browser tabs.
Reset times and pace warnings. Not just a leftover percentage. Pane tells you when a window resets and when your current burn will run it out early.
Local spend. A shared dollar (or token) donut priced from the logs your CLIs already write, on your PC.
No extra account. If you already signed into Claude Code, the Codex CLI, Cursor or Copilot on this machine, the card is already there.
How Pane relates to OpenUsage
OpenUsage is the original Mac project, by Robin Ebers, MIT licensed. Pane grew from that work: same problem, same honest local-first stance, rewritten for Windows with Tauri instead of a Mac menu-bar stack.
The two apps are not the same binary. Features land on their own clocks. If you are on a Mac, use OpenUsage. If you are on Windows, use Pane. That is the split.
Install the Windows port
- In any terminal:
winget install Pane.Pane - Or download the installer from the Pane homepage.
- Click the tray icon next to the clock. Signed-in tools show up on their own.
Track more than one tool
Most people who want OpenUsage on Windows are paying for more than one AI plan. Pane is built as an AI plan tracker for that stack, not as a Claude-only meter.
Questions
Is there an OpenUsage for Windows?
OpenUsage itself is a Mac menu bar app. Pane is the OpenUsage Windows port: a free, MIT-licensed tray app that tracks the same kind of AI plan limits next to the clock.
Is Pane the same as OpenUsage?
Same idea, different operating system. OpenUsage lives in the Mac menu bar. Pane is a from-scratch Windows port that shares provider research with OpenUsage and sits in the Windows system tray.
How do I install OpenUsage on Windows?
You do not install OpenUsage on Windows. Install Pane instead: winget install Pane.Pane, or download the installer from this site. On a Mac, use OpenUsage.
