HTTP Header Checker
Fetch any URL and inspect its HTTP response: status code, redirects, timing, every response header, and a security header audit with a score and letter grade.
Frequently asked questions
What does this tool check?
It requests a URL and reports the status code, redirect count, elapsed time, the full list of response headers and a security header audit.
How is the security score calculated?
Each recommended header carries a weight; the score is the share of present weight out of the total, mapped to a grade from A down to F.
Should I follow redirects?
Follow them to inspect the final response, or turn it off to see the first response and count each hop in the chain.
