HTTP Header Viewer
See every response header a URL returns, with what each one does and a security header audit.
SEO & Marketing
Check what status a URL returns and follow its redirect chain, hop by hop, with timings.
This tool asks our server to perform the lookup. What you enter is used for that request only and is not stored. How privacy works
Requests a URL from our server and reports the status code, what it means, and every redirect between the address you typed and the page that finally answers - each hop with its own code, the address it points to, the time it took and the IP it came from.
That chain is what matters for SEO: a 302 where a 301 belongs, a chain three hops long, or a redirect that quietly drops from HTTPS to HTTP all cost you. You can also turn following off to see a redirect exactly as it is sent.
Only public http and https URLs can be checked, and some sites answer an automated request with 403 even though they open fine in a browser.
