PixelProbe is a Chrome extension designed to assist frontend developers by providing precise measurements between HTML elements on live websites. It eliminates the need for manual calculations in browser DevTools, bringing a user-friendly measurement interface similar to Figma directly to any webpage. Users can hover over elements while holding the Alt/Option key to view dimensions, distances, and box model values, all presented with a familiar visual style that enhances usability for design verification tasks.

This tool is built for efficiency, requiring zero setup and offering keyboard-driven activation for seamless measuring. Configurable hotkeys allow users to customize their experience, and its cross-site compatibility ensures it works on various environments, including production and localhost. With a strong focus on privacy, PixelProbe performs all measurements locally without data collection, making it an indispensable tool for developers, UI engineers, QA testers, and designers aiming for precision in their work.
