Browser Variable Helper is a Chrome DevTools extension designed for frontend developers seeking to enhance their CSS auditing process. This free tool identifies hardcoded values, fallback values, and undefined CSS variables, providing visual indicators directly in the DOM tree and CSS panel. Each issue is color-coded and comes with explanations to streamline the debugging process and facilitate the adoption of a token-based design system.

To use the Browser Variable Helper, simply install the extension and open Chrome DevTools. By navigating to the 'Browser Variable Helper' tab, developers can click on any element to inspect its styles and see highlighted issues. Importantly, the extension operates entirely locally, ensuring that no data is collected or transmitted, allowing for a secure and efficient workflow.
