Claude Usage Badge

Unofficial Claude usage badge: session, weekly limits (all models/Sonnet/Opus/Fable/Design), extra usage, and plan tier.

See your Claude usage at a glance — right in the toolbar. Claude Usage Badge adds a small badge to your browser toolbar showing your current session usage percentage. Click it to see a detailed breakdown: • Session (5-hour) usage bar with reset countdown • Weekly (7-day) usage bar with reset countdown • Extra usage status: ON/OFF, IN USE indicator, approximate spend, limit, and remaining balance • Subscription tier display (Free, Pro, Team, Max) How it works: The extension reads Claude's own usage API (the same data Claude's frontend uses) to show your real utilization numbers. A lightweight content script detects when you send messages and triggers a refresh. Usage also refreshes automatically every 3 minutes. No data leaves your browser. No third-party servers. No analytics. No tracking. Permissions explained: • Storage: persists your usage state between browser restarts • Cookies: reads your Claude org ID to call the usage API • Alarms: periodic background refresh every 3 minutes • Host permission (claude.ai): required to read usage data from Claude's API Open source. Minimal. Private.
