Redirect & Header Checker

Redirect & Header Checker shows what really happened between the address you typed and the page you landed on. REDIRECT CHAIN • Every hop with its HTTP status code: 301, 302, 307, 308, and client-side meta-refresh or JavaScript redirects • What changed at each hop: HTTPS upgrade, www added or dropped, trailing slash, path or query change • Server IP, time per hop, protocol (HTTP/1.1, HTTP/2, HTTP/3) and total time to the final response • Warnings for redirect loops, chains with several hops, temporary redirects on permanent moves, and HTTPS to HTTP downgrades RESPONSE HEADERS • Final page headers grouped into Indexing and SEO, Caching, Security, and Server • Raw view and a filter box • Each hop expands to show its own headers CHECKS • X-Robots-Tag noindex or nofollow • Strict-Transport-Security, Content-Security-Policy, X-Content-Type-Options, X-Frame-Options, Referrer-Policy, Permissions-Policy • Compression, HTTP version, charset, CDN cache status, server version disclosure TRACE ANY URL Type any URL into the box and the extension traces it in a hidden tab, without your cookies, then closes the tab. Perfect for checking the http:// or www version of a page before you fix a redirect. Copy the chain, copy the headers, or export the whole trace as JSON. PRIVACY Nothing leaves your browser. The extension only observes the navigation events your browser already performs, keeps them in session storage until the tab closes, and never contacts any server of its own.
