Paste or upload HTML and DOM Lens builds a live element tree. Click any node to see its code, IDs, classes and every CSS rule that applies — with overridden and invalid declarations clearly flagged — plus an accessibility & quality score. Includes a full kit of developer tools.
Everything runs on your device — nothing is uploadedPaste a page's HTML (View Source → copy), or drop an .html file here. A URL can't be fetched in the browser without a server, so DOM Lens works on the markup you provide — keeping everything private.
Parses the <head> and content of the HTML you loaded in the Inspector. For live IP / hosting / server-tech lookups, those require a server request to the remote site — see the note below.
Load HTML and run the analysis to preview how this page looks in search results and social cards.
IP address, web-hosting technology and live server headers can't be read in the browser — the same-origin policy blocks it, and reading them needs a server to fetch the remote site. DOM Lens keeps everything on your device by default. If you want those, open a dedicated third-party service in a new tab — this sends the domain to them, not to Azad.
Enter one selector per line to see its (ids, classes, elements) weight and which one wins.
Decodes header & payload locally. Signature is not verified (that needs the secret) — never paste production secrets.
