Honest scope: browser CORS rules block reading response headers from other domains, so this can tell you whether a URL redirects (using
redirect: "manual" and checking for an opaqueredirect response) but not the destination URL, status code (301 vs 302), or number of hops — no free client-side tool can show that for an arbitrary external site. For full redirect-chain details, use your browser's own Network tab (F12) on the actual page. Everything here runs entirely in your browser.
