Redirect Radar — HTTP Redirect Checker & Chain Tracer for Chrome Click a link and see where it actually goes. Redirect Radar follows every HTTP redirect hop-by-hop — surfacing status codes, response headers, cookies, and a security grade — all live from a Chrome popup. Your URLs and headers never leave your browser. LIVE REDIRECT CHAIN TRACER Watch 301, 302, 303, 307, and 308 redirects stream in as the page loads. Each hop shows: status code, HTTP method, protocol, timing, and the full destination URL. Spot redirect loops and unnecessary hops before they reach production. URL INSPECTOR Click any hop to decode it: protocol, host, port, path, and every query parameter — listed flat and human-readable. Untangle UTM chains, OAuth callbacks, and tracker blobs in seconds. HTTP RESPONSE HEADERS VIEWER A terminal-style panel shows every response header for each hop. Click any row to copy the key:value pair. Scan for Location, HSTS, Content-Security-Policy, and Set-Cookie at a glance. COOKIE ANALYZER Every Set-Cookie header listed with Secure, HttpOnly, and SameSite attribute badges. Values masked by default — click to reveal, with a warning. SECURITY GRADE A–F Get a letter grade based on: HSTS enforcement, mixed-content warnings, HTTPS downgrade hops, third-party cookies, and missing CSP. A screenshot-ready score you can share with a stakeholder. EXPORT IN ONE CLICK Copy the full redirect chain as cURL, Markdown, JSON, or HAR. Reproduce any redirect in your terminal, drop it in a bug ticket, or feed a script — in two seconds. WHO IT'S FOR Frontend developers — debug OAuth flows, SSO callbacks, and broken redirects without opening DevTools. QA engineers — capture HAR files and cURL reproducers and attach them to tickets in one click. Security engineers — catch HTTPS downgrade hops, tracker chains, and cookie misconfigurations. Digital marketers — verify affiliate links and UTM parameters survive every click-tracker. Support teams — diagnose "this link is broken" tickets before escalating. PRIVACY Your URLs, headers, and cookies are never transmitted. Trace data stays entirely on your device. The extension sends only anonymous usage events (e.g. popup_opened) — never URLs, headers, or page content. FREE No ads. No subscription. No account required. The full feature set stays free forever.
