Quota Monitor for Claude

See your Claude subscription usage — current session and weekly limits with live reset countdowns.

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 highest usage percentage — session or weekly, whichever is closer to its limit — 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. This extension is an independent project and is not affiliated with, endorsed by, or sponsored by Anthropic. "Claude" is a trademark of Anthropic, PBC. - - - New in 1.0.3 • Toolbar badge now shows whichever of your session or weekly limit is higher — so a used-up weekly quota no longer hides behind a fresh 5-hour window showing 0%. A "W" prefix (e.g. W85) tells you the weekly limit is the one on the badge. • New setting under Toolbar badge: switch back to "Current session only" if you prefer the previous behaviour. New in 1.0.2 • Fixed: Plan label (Pro / Max / Max 5x) now updates immediately when you upgrade or downgrade your subscription. Previously the label could stay stale until the extension was reinstalled or the organization was switched.
