VibeMeter is a native macOS menu bar application designed to help users track their AI service spending, primarily focusing on Cursor AI and Claude. It offers real-time monitoring, customizable notifications, and multi-currency support, providing a clear overview of AI costs directly from the menu bar.

How It Works

VibeMeter employs a native macOS architecture using Swift 6, SwiftUI, and AppKit. For Cursor AI, it uses secure web authentication and API integration to fetch usage data directly from the provider's servers, syncing every 5 minutes. For Claude, it analyzes local log files (~/.claude/projects/) with user permission, tracking usage within a 5-hour window and calculating costs using OpenAI's o200k_base encoding. The application features an animated gauge display that dynamically switches between showing request usage percentage or monetary spending percentage based on user configuration and current usage.
