Claude Usage Monitor for Windows (github.com)

The newly launched Claude Usage Monitor is a lightweight native Windows application designed to help users track their Claude Code utilization efficiently. Version 1.0.0 provides a clear overview of key metrics such as session tokens, current context window usage, and account limits set by Anthropic, all in a minimalistic interface. Unlike many other monitoring tools, this application is built entirely in C11 using Win32, eliminating the need for runtime installations, third-party libraries, or telemetry collection—ensuring user privacy and security. This tool fulfills a growing demand within the AI/ML community for local, simple solutions to monitor resource usage without the overhead of larger applications. By directly reading the local Claude Code session data and utilizing Anthropic's usage endpoint, it gives users real-time insights into their current session and account-level quotas. As its source code is freely available for inspection, it enhances transparency and user trust, making it an appealing choice for developers and researchers seeking to optimize their Claude Code experience while maintaining control over their data.
