AI API Balance Monitor

This browser extension provides comprehensive tracking for your large language model API usage across 11 different providers. Key features: • Multi-provider API cost tracking • Real-time spending charts (raw SVG rendering) • Local data storage for enhanced privacy • Support for custom API proxies and distribution hubs • Intuitive Liquid Glass UI with smooth animations Unlike most trackers that focus solely on a single provider, this tool offers a unified view of your consumption, helping you make informed decisions about resource allocation.

Your sensitive API keys and usage data remain encrypted and stored exclusively on your local machine, guaranteeing complete privacy and security. The extension is ideal for developers, researchers, and teams managing multiple language model accounts who need to monitor API costs and token usage efficiently. It supports major models like DeepSeek, Claud, Gemini, and Moonshot, and allows customization of Base URLs to integrate with personal API agents or distribution relays.
