HTTP Header Checker

Fetch a URL and inspect status, redirects, and security headers.

Why this exists

'The site loads weird' or 'is HTTPS set up right?' is answered by the response headers. Seeing the redirect chain, HSTS, CSP, and cache headers in one shot beats curl -I from a box you may not have.

How to use
  1. Enter a URL (https:// assumed if you omit it).
  2. Tool follows redirects and reports each hop's status.
  3. Final response headers are listed, with security headers (HSTS, CSP, X-Frame-Options) called out.

Worked example

Try example.com, https:// is assumed, redirects are followed hop by hop, and the final response's security headers are called out.
