Show HN: Claude Usage Tray – Windows Tray for Claude Code Rate Limits (github.com)

A new Windows system tray application, Claude Usage Tray, has been released, offering users a quick, visual representation of their Claude Code rate limit usage. By displaying a colored circle next to the system clock, users can easily assess their session and weekly usage percentages—green for under 70%, amber for up to 89%, and red for 90% or more. This tool addresses the challenge of sudden cutoffs during development by providing real-time visibility into usage limits, which is particularly significant for developers relying on Claude Code for their projects. Claude Usage Tray is notable for its simplicity and efficiency; it operates through a lightweight PowerShell script that requires no additional installations or admin rights. The application polls Anthropic's API every five minutes to update the usage metrics, ensuring that developers can make informed decisions without interrupting their workflow. The implementation respects user privacy by keeping the OAuth token secure and making minimal network calls, embodying a user-friendly approach to managing usage limits. Although it is an unofficial tool, its independence and straightforward functionality make it a valuable addition for developers using multiple IDEs.
