DOMOwl

About

Your page looks fine in the browser. But what does the HTML source actually say?

DOMOwl fetches the raw HTML and compares it with the live DOM. The difference is what JavaScript added, removed, or changed after the page loaded. That gap is what search engine crawlers and AI agents might not see.

ONE CLICK SCAN
Hit scan on any page. DOMOwl highlights JS-injected elements directly on the page: links in amber, headings in purple, images in blue. You see exactly where on the page the differences are.

AUTO-SCAN
Turn it on and DOMOwl scans every page you visit. A badge on the icon shows the number of differences. Zero means the page is fully static. 50+ means something needs attention.

FULL REPORT
Opens in a new tab. Every element compared side by side: source HTML on the left, rendered DOM on the right. Differences sorted to the top, matching elements below.

WHAT IT CHECKS
Links (with URL, anchor text, and DOM location)
Headings H1 through H6
Title tag, meta description, meta robots, canonical URL
Open Graph and Twitter Card tags
Structured data / JSON-LD (property level)
Images with alt attribute audit
Hreflang tags
Word count and text content diff
DOM node count and render timing
Cookie/consent elements flagged automatically

EXPORT
Download CSV for Excel or copy to Google Sheets. Each export includes URL, status (DOM only / Source only / Both), anchor text, and DOM location.

PRIVACY
All processing happens in your browser. No data is sent anywhere. No analytics. No tracking. No accounts. One network request per scan: fetching the URL you chose to scan.

Built for SEO consultants, developers, and anyone who needs to know what crawlers actually see.
