Show HN: Windows Taskbar Monitor for Claude Code Usage (Rust, Open Source) (github.com)

A new open-source Windows taskbar widget, designed for tracking Claude API rate limit usage, has been introduced. This lightweight tool integrates directly into the Windows taskbar, featuring two progress bars that show real-time data on session and weekly usage, along with countdowns until the rate limit resets. It operates by reading the Claude OAuth token and making minimal API requests to the Anthropic Messages API to extract rate limit data, updating every 15 minutes or at a user-defined frequency. This development is significant for the AI/ML community as it provides a straightforward way for developers utilizing the Claude API to monitor their usage effectively, ensuring they stay within usage limits and optimize their application performance. Built using the Rust programming language, the tool supports Windows 10 and 11, detecting system dark/light modes automatically. Its simplicity allows users to run it without needing the Rust toolchain, making it accessible to a broader audience. This widget not only enhances user experience but also fosters better resource management for those leveraging Claude's services.
