Quota Monitor for Claude

About

Keep an eye on your Claude subscription limits without opening settings.

Quota Monitor for Claude shows the same usage data as the claude.ai usage page — right in your toolbar:

• Current session (5-hour window), weekly all-models, and per-model weekly limits
• Live countdown to each reset, plus the exact local reset time
• Toolbar badge with your current session percentage, refreshed every 5 minutes
• One-time notification when any limit crosses 90% — once per reset window, no nagging
• Shows your plan (Free, Pro, Max) and supports accounts with multiple organizations
• Optional fallback: paste a Claude Code OAuth token to monitor usage without a claude.ai session

Zero setup: if you're signed in to claude.ai in this browser, it just works. No account creation, no analytics, no external libraries.

Your data stays yours: the extension talks only to claude.ai and api.anthropic.com, stores its cache locally in your browser, and sends nothing anywhere else.
