Headers inspector
HTTP headers and redirect checker
Follow every redirect from the address you type to the final page, then read the response: status, HTTP version, timing, compression, caching and graded security headers. Use it for redirect loops, a slow first byte or a security review.
We check from the outside, the way visitors see your site, and keep a simple log of sites checked. Privacy policy.
How it works
What this checks
- Redirect chain Every hop with its status code, location and timing, and whether http:// ends up on https://.
- Response The status code, HTTP version and every response header the server sends.
- Speed Time to first byte, page size and whether compression is switched on.
- Caching and cookies Cache-Control and related headers, whether a page cache answered, and the security flags on cookies.
- Security headers HSTS, Content-Security-Policy, X-Content-Type-Options, frame protection, Referrer-Policy and Permissions-Policy, each graded with a suggested value.
