HTTP Header Inspector & Security Analyzer
HTTP headers reveal a lot about how a server is configured — caching behavior, security policies (CSP, HSTS), CORS rules, and server software. This tool fetches and displays the full header set for any public URL.

-
Enter Public URL: Type the complete domain or endpoint URL.
-
Inspect Response: Click Inspect to analyze response headers, status codes, and protocols.
