CSS Footprint is a free Chrome add-on designed for web developers to efficiently track changes made to CSS in the Chrome DevTools. This tool addresses the common issue of losing track of CSS edits by automatically monitoring modifications in the Elements → Styles panel. With its live tracking feature, users can easily see a clear diff of additions, modifications, and deletions in their CSS, similar to Git functionality. The tool is particularly useful for developers who often tweak styles and need a reliable way to document those changes.

The add-on boasts a smart diffing engine that highlights changes for better visibility, and it intelligently manages dynamically injected style tags to prevent potential conflicts. Additionally, CSS Footprint offers noise reduction options to filter out unnecessary inline styles, ensuring that users focus on meaningful changes. With zero setup required, CSS Footprint integrates seamlessly into the Chrome DevTools, providing a user-friendly experience that prioritizes privacy by operating entirely locally.
