OpsBench

HTTP Header Analyzer

Security headers, compression, protocol, redirects, cookies and caching — all in one.

● Runs on our server
From a single server request: security headers with a grade, compression (Brotli/Gzip), HTTP version and HTTP/3 support, the redirect chain, cookies, caching, and all raw headers. HTTP/3 is detected via the Alt-Svc header (advertised, not an actual handshake).

How it works

Our server requests the URL with curl, follows redirects, and collects every response header. We grade security headers, detect HTTP/2 and HTTP/3 (via Alt-Svc), compression, cookies and caching, and recognise Cloudflare bot-blocking responses.
