About the iHACKER Header Checker

The iHACKER Header Checker fetches a URL and shows you everything the server returns: the full set of HTTP response headers, the redirect chain to the final page, a security-header grade, and the page's SEO metadata — title, meta description, canonical, robots and Open Graph tags.

Security-header grade

We check for the six headers that matter most for browser security — HSTS, Content-Security-Policy, X-Frame-Options, X-Content-Type-Options, Referrer-Policy and Permissions-Policy — and grade the response A to F based on how many are present.

What you can do with it

• Debug 301/302 redirects and confirm the final destination URL.
• Audit security headers and spot what's missing.
• Check SEO basics — title, description, canonical and OG tags — in one view.
• Read server, content-type, caching and cookie headers at a glance.
