What It Does

OpenUsage lives in your menu bar and shows you how much of your AI coding subscriptions you've used. Progress bars, badges, and clear labels. No mental math required.

• One glance. All your AI tools, one panel.
• Always up-to-date. Refreshes automatically on a schedule you pick.
• Global shortcut. Toggle the panel from anywhere with a customizable keyboard shortcut.
• Lightweight. Opens instantly, stays out of your way.
• Plugin-based. New providers get added without updating the whole app.
• Local HTTP API. Other apps can read your usage data from 127.0.0.1:6736.

Open Source, Community Driven

OpenUsage is built by its users. Hundreds of people use it daily, and the project grows through community contributions: new providers, bug fixes, and ideas.

I maintain the project as a guide and quality gatekeeper, but this is your app as much as mine. If something is missing or broken, the best way to get it fixed is to contribute by opening an issue, or submitting a PR.

Plugins are currently bundled as we build our the API, but soon will be made flexible so you can build and load their own.

How to Contribute

• Add a provider. Each one is just a plugin. See the Plugin API.
• Fix a bug. PRs welcome. Provide before/after screenshots.
• Request a feature. Open an issue and make your case.

Keep it simple. No feature creep, no AI-generated commit messages, test your changes.

Built Entirely with AI

Not a single line of code in this project was read or written by hand. 100% AI-generated, AI-reviewed, AI-shipped — using Cursor, Claude Code, and Codex CLI.

OpenUsage is a real-world example of what I teach in the AI Builder's Blueprint — a proven process for building and shipping software with AI, no coding background required.
