HTTP security headers analyzer

Paste response headers to check browser security policies and cookie attributes.

Local paste analyzer; no URL request, no input submission, no ranking label, no full security audit. Input limit is 64 KiB.

The profile only changes recommendation weight and ordering; it does not request URLs, read or write URL parameters, or persist input.

Paste response headers, then analyze. This page does not request URLs or submit input to the backend.
