--- ## Overview ClaudeChecker sits quietly in your menubar and tracks your Claude API quota usage across both the 5-hour and 7-day windows — so you always know how much runway you have left before hitting a rate limit. No API key required. It reads directly from your `claude.ai` session using a built-in browser login — the same data the Claude web app uses. --- ## Screenshots
