methol/usage-bar

UsageBar is a small macOS menu bar app that shows how much of your Claude, Codex, or Gemini usage allowance you have used, without needing to open a browser and check a usage page. A compact icon sits in the menu bar with a mini bar chart for both the short five hour window and the longer seven day window, and clicking it opens a detailed popover with per model breakdowns and reset timers. The popover lets you switch between tabs for Claude, Codex, and Gemini, so if you use more than one of these services you can track them all from the same app. It also shows extra usage cost estimated in US dollars using public pricing data, and a history chart so you can see how your usage has changed over recent hours, days, or weeks. Hovering over the chart reveals the exact values at any point in time. Signing in is meant to be simple: Claude uses OAuth through your browser so you never handle an API key directly, while Codex and Gemini read credentials that are already saved by their command line tools. The app checks your usage on a configurable schedule, such as every thirty minutes, and can check for its own updates automatically. To install it, you download a disk image from the project's releases page and drag the app into your Applications folder, or build it from source using Xcode if you prefer. It requires macOS fourteen or later, known as Sonoma, and runs natively on both Apple Silicon and Intel Macs as a single universal binary. The app is aimed at people who use Claude, Codex, or Gemini command line tools regularly and want an at a glance way to avoid hitting rate limits unexpectedly.
