How it works
Paste raw HTML or, if you're lucky and the target site is CORS-permissive, point it at a URL. The tool runs the markup through the browser's DOMParser, walks the <head>, and pulls out the things that matter for SEO and link previews: title, description, keywords, robots, viewport, charset, canonical, hreflang, favicon, every og:* tag, and every twitter:* tag.
No backend, no proxy, no logging. Everything happens in your tab.
When to use it
- Quick sanity check after deploying a page: did the right canonical ship?
- Auditing a competitor's OG setup before you write your own.
- Debugging a link preview that looks wrong in Slack or LinkedIn.
The URL field will fail on most production sites because of CORS. That's expected. Open the page, view source, paste the HTML here.
