pixelDiff iframe Tracker is a free Chrome extension designed to enhance the capabilities of the pixelDiff web app, which is a tool for comparing designs with live web implementations. This extension offers several key features including automatic iframe height tracking, allowing users to monitor the height of embedded content in real-time and update it dynamically as the content changes. It also effectively handles infinite scroll pages, making it a reliable choice for modern web applications.

In addition to height tracking, the extension provides full-page screenshot capabilities, enabling users to capture long scrollable pages seamlessly with automatic stitching for high-quality results. It includes CSS property inspection tools that allow users to view and edit style information on hover, as well as real-time URL change detection, particularly useful for Single Page Applications. With a focus on privacy, the extension operates solely within the pixelDiff web app and does not transmit user data.
