HTTP Header Inspector
Read response headers, status and redirect chain for a URL.
Input
This tool sends only the URL you enter to our server, which fetches that public page. Nothing else is stored.
Result
Enter a public URL and run the check.
About this tool
Requests a URL server-side and lists the final status, redirect chain, content type, caching headers and security headers, with a pass/fail note for the important ones. Requests are bounded and cannot target private networks.
How to use it
- Enter a public URL.
- Press Inspect to fetch headers only.
- Review caching, compression and security headers.
Frequently asked questions
Why does the final URL differ from mine?
The server redirected. The chain shows every hop so you can see where and why.
Which security headers should be present?
At minimum X-Content-Type-Options, a Referrer-Policy and, over HTTPS, Strict-Transport-Security. CSP and Permissions-Policy add stronger isolation.
