- Security: headers like HSTS, CSP, X-Frame-Options and X-Content-Type-Options protect against common attacks.
- Performance: caching and compression headers affect how fast your site loads.
- SEO & behavior: status codes and redirects tell search engines and browsers how to treat your pages.
- The raw response headers for every step in the redirect chain.
- The final HTTP status code and resolved URL.
- Server, content-type, security and caching headers where present.
- Enter your domain (e.g., example.com) and click Check.
