Claude Usage Monitor

Automatically displays your Claude API usage (5-hour and 7-day limits) as sleek progress bars directly on claude.ai.

See your Claude.ai usage at a glance — no popup, no options, no setup required. Claude Usage Monitor automatically displays your 5-hour and 7-day usage limits as sleek progress bars directly in the claude.ai interface. No configuration needed — it just works. ✨ Features: • Real-Time Limit Detection: Intercepts streaming completion frames and rate limit events so your usage stays accurate on all tiers (Free, Pro, Team). • Live Relative Countdowns: Displays clear time remaining until your 5h and 7d windows reset (e.g., "resets in 3h 10m"). • Seamless 7-Day Persistence: Retains 7-day usage and multi-model limit data across browser refreshes and tab switches. • Never Rolls Back: Freshness-aware updates ensure the bar always shows your newest usage — rapid messages can no longer revert it to an older percentage. • Rock-Solid Visibility: Survives composer re-renders, notice dismissals, and interface updates — the bar stays exactly where you left it. • Works Everywhere: Full support for regular chats, Claude Projects, and new conversations. • Modern Status Strip: Clean glassmorphic design positioned directly beneath the chatbox without blocking composer action buttons. • Smart Auto-Refresh: Automatically refreshes usage when messages complete or when a reset window boundary passes. • Multi-Account & Workspace Support: Automatically tracks active workspace organizations and switches limits seamlessly. • Dark & Light Theme Adaptation: Dynamically adapts to match Claude.ai's color palette. • Zero Footprint: No popup, no options page, runs entirely in the background. • Accessible & Lightweight: Built with semantic ARIA progress bars and pure TypeScript (zero framework bloat). 🚀 What's New in v1.2.0: • Freshness arbitration: usage bar no longer rolls back to stale values on rapid messages. • 7-day limit no longer flickers to 0% during partial updates. • Clean in-flow layout: positioned directly beneath the composer without overlapping the chat input or project Recents. • Full Claude Projects support: displays directly on project pages (/project/{id}) and all project conversations. • Widget survives dismissing Claude's usage notice and interface re-renders. • Accurate Idle state: correctly displays 0% and "Idle" for idle accounts and freshly reset windows. • Seamless theme sync: instantly adapts to Claude's latest dark and light mode settings. • Faster limit updates via a persistent in-session cache. • Improved extension loading reliability across Chrome and Firefox. 🛡️ Privacy & Security: • Minimal Permissions: Requires only "storage" — zero unnecessary high-privilege permissions. • No Tracking & No Telemetry: Zero analytics, zero data collection, zero third-party servers. • Local Only: All limit computations and data stay strictly in your browser. • Open Source: Full source code available on GitHub for complete auditability. Perfect for power users, developers, and professionals who want to monitor their Claude limits without ever leaving the claude.ai interface.
