🔥 BurnRate

A macOS menu bar app that tracks your Claude Pro/Max usage in real-time — so you never get rate-limited by surprise.

Why?

Claude Pro and Max have usage limits that reset on different schedules. You're mid-conversation, deep in thought — then suddenly rate-limited. BurnRate sits in your menu bar so you always know where you stand.

Quick Start

1. Download BurnRate_0.1.0_aarch64.dmg from Releases
2. Open the DMG and drag to Applications
3. Right-click → Open (not notarized yet)
4. Sign in to Claude when prompted
5. Done! Check your menu bar ⚡

Features

• Menu bar at a glance: ⚡41% 3h 01m | 🔋11% — session usage, reset countdown, weekly usage
• Dashboard: Click to see detailed breakdown with visual progress bars
• Session tracking: Current session usage % with countdown to reset
• Weekly tracking: All models + Sonnet-specific usage
• Extra usage: Monthly spend vs limit (e.g. $39.37 / $50.00) — Max plan
• Background polling: Auto-updates every 60 seconds
• Zero config: Just log in to Claude once — no API keys needed
• Lightweight: Native macOS app via Tauri, minimal CPU/memory
• Works with Claude Pro and Max plans

How It Works

BurnRate opens a hidden browser window, authenticates with your Claude account, and reads usage data from claude.ai/settings/usage. The window stays offscreen — you never see it.

1. Launch BurnRate → appears in menu bar
2. First launch: Claude login window appears → sign in once
3. Done! Usage data auto-refreshes in the background

Build from Source

# Prerequisites: Rust, Node.js 18+
cd frontend
npm install
npx tauri build

Output: frontend/src-tauri/target/release/bundle/macos/BurnRate.app

Privacy & Security

• 100% local — no external servers, no telemetry
• No API keys — uses browser session cookie only
• No stored passwords — auth handled by Claude's own login
• Claude session lives in an isolated macOS WebView (WKWebView)
• ⚠️ This app scrapes claude.ai — technically against Anthropic's ToS. Use at your own risk.

Tech Stack

• Tauri v2 — Rust + native WebView, ~5MB bundle
• Svelte — Dashboard UI
• Rust — Polling loop, tray management, scraping coordination
• Custom URL scheme — burnrate://result/<base64> for WebView → Rust IPC

Known Issues

• Intel Mac build not yet available (ARM/Apple Silicon only)
• Login cookies may not persist after macOS restart (WKWebView limitation)
• Window briefly appears during initial login flow
• Tested on Claude Max. Pro users: please open an issue if anything looks off!
