Show HN: Monitor Claude/Codex usage on Linux via browser cookies (no API keys) (github.com)

A new tool has been introduced that allows Linux users to monitor their Claude Code and OpenAI Codex usage directly from the Waybar status bar, leveraging browser cookies for authentication without the need for API keys. This innovative solution provides real-time updates on usage limits, displaying data such as remaining quotas and countdown timers. The tool is particularly significant for developers who rely on AI-powered coding assistants, as it helps them manage their usage effectively by providing clear visual indicators of their consumption levels with color-coded warnings ranging from green to red. The technical implementation utilizes Python and the `browser_cookie3` library to fetch authentication cookies from Chrome, ensuring ease of access for users. It features a variety of commands for both usage monitoring and configuration, with options to customize browser choices and automate refresh intervals. Additionally, it offers built-in error handling and automatic retries on failures. By simplifying the process of tracking AI tool usage and integrating seamlessly into the user's current workflow, this tool enhances productivity for developers engaged in AI-assisted coding tasks.
