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. • 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 v1.1.0: • New stream-based rate limit parser for instant 5h/7d limit detection. • Multi-window local storage persistence across sessions. • Redesigned status strip under the composer for zero button interference. • Enhanced Safe Browsing compliance — dropped unnecessary cookie permissions. • Added localized reset date tooltips and screen-reader accessibility tags. 🛡️ 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.
