TokenBar: Open-Source Quota Monitor for Codex, Claude and Cursor Across Five OSes

⚡ The gist in 5 seconds - TokenBar has appeared on GitHub — an open-source cross-platform monitor for AI service quotas. - A single Flutter codebase covers Windows, macOS, Linux, Android, and iOS. - The list of sources includes Codex, Claude, Cursor, and 47 more services — 50 in total. ### 🔍 What was found The project lives in the lwh0630/TokenBar repository. The author describes it as an open-source quota monitor: the app shows how much of your limit remains across 50 AI services, including Codex, Claude, and Cursor. Five platforms — Windows, macOS, Linux, Android, and iOS — are built from a single Flutter codebase. The mechanics aren't explained in the description: how exactly TokenBar reads the remaining quota — via provider APIs, local tokens, or web interface scraping — is unclear from the annotation. Neither the version, nor the build number, nor the list of the other 47 services is specified. You'll have to check the README and source code at github.com/lwh0630/TokenBar for all of that. ### 💡 Why it matters A typical geek scenario is running three or four paid subscriptions at once: Codex for code, Claude for writing, Cursor as the editor. Each service counts its limits in its own interface, and you have to check them one by one. A single dashboard on top of all services eliminates that back-and-forth — and the fact that the project is open-source and built with Flutter opens the door to quick forks for your own providers. How accurately TokenBar tracks quotas remains to be seen: there's no public README with implementation details in the description yet.
