ClaudeBar and OpenLimiter
The clearest per provider documentation, and explicit remaining quota bands.
- Platform
- macOS 15 or later. Installed with Homebrew, a release download, or from source.
- Licence
- MIT
- Coverage
- Claude, Codex, Gemini, GitHub Copilot, Antigravity, Z.ai, Kimi, Kiro, Amp, OpenCode Go, Oh My Pi and Grok.
- Source
- Mixed, and documented per provider: mostly by running each vendor's command line tool, plus a local database for OpenCode Go, local credentials for Grok, and an optional browser cookie path for Kimi.
What it does
It is a macOS menu bar application that monitors the usage quotas of AI coding assistants. For most providers it runs that vendor's own installed command line tool and reads the result.
What it does well
It documents exactly how every single provider is read, which is rarer than it should be, and it publishes explicit remaining quota bands: healthy above 50 percent, warning between 20 and 50, critical below 20, depleted at zero.
Where OpenLimiter differs
There is no documented command line tool, JSON export or local endpoint, so nothing downstream can consume what it shows. It is a display surface for human eyes. Its per provider reliance on each vendor tool being installed also means coverage quietly shrinks on a machine that lacks them.
Before you go looking
A second repository carries a near identical description. Whether it is a fork, a mirror or an independent project was not confirmed, so use the repository linked here.
How these were checked
These notes were read off each project's own repository, README or store listing in August 2026. Software moves, so check the source before you rely on any of it, and open an issue if something here has gone stale or is simply wrong.
