Security Headers Inspector – Check HTTP Headers for Protection

HTTP security headers help protect users by enforcing secure communication rules within the browser. Headers like Content-Security-Policy, X-Frame-Options, X-Content-Type-Options, and Referrer-Policy reduce attack surface areas — preventing clickjacking, MIME sniffing, and data leakage.

This tool inspects a website’s HTTP headers using JavaScript’s fetch() and HEAD requests. It quickly checks for the presence of major security headers and highlights missing or weak configurations. Although limited by browser permissions, it gives a fast, client-side view ideal for auditing public-facing sites without server calls or browser extensions.
