FigDiff is a Chrome extension designed to facilitate the visual comparison of Figma designs with actual web page implementations. This tool enables developers to verify that web pages meet design specifications, thereby enhancing communication between designers and developers and improving the accuracy of design implementations.

Key features include the ability to input Figma design URLs, which are automatically validated for correctness. Upon submission, FigDiff analyzes the differences between the active web page and the specified Figma design, presenting the results through a visual overlay. Users can adjust the opacity of design elements in real-time using a slider and monitor the comparison process with a progress bar. Additional functionalities include OAuth authentication for Figma accounts, saving comparison results, and options for retrying or returning to the input screen.
