DOMOwl is a Chrome add-on designed to help users understand the differences between the raw HTML source of a webpage and its rendered DOM. This tool is essential for SEO consultants, developers, and anyone interested in what search engines and AI agents might miss. With features like one-click scanning and auto-scan, users can easily identify JavaScript-injected content that alters the original HTML structure. The interface highlights differences directly on the page, making it easy to see changes in links, headings, images, and more.

In addition to highlighting differences, DOMOwl provides a comprehensive report that compares the source HTML with the rendered DOM side by side. Users can export the data in CSV format for further analysis in Excel or Google Sheets. Privacy is a key feature, as all processing occurs locally within the browser with no data transmission, ensuring a secure experience. Overall, DOMOwl is a valuable tool for optimizing web content visibility.
