## Description

See where every link really goes.

Redirect Inspector shows every HTTP redirect chain in real time — 301, 302, 303, 307, 308, HSTS upgrades, meta-refresh and JavaScript redirects — straight from the webRequest API. Check any URL without opening it, expand shortened links, audit redirect chains for SEO, and catch loops, ping-pong hops and broken destinations before your visitors do.

<strong>Why Redirect Inspector</strong>
<ul><li>Live capture — every redirect is recorded as you browse, no manual trigger</li><li>Check any URL — paste it into the bottom dock and get the full chain without visiting the page</li><li>Readable chains — status codes, hop count and total duration; same-host hops show what changed (http → https, trailing slash)</li><li>Short link expander — see the real target of shortened or masked links</li><li>Search &amp; noise filter — filter chains by URL; tracking pixels and media requests hidden by default</li><li>Powerful export — summary, full report, raw JSON download, or a ready cURL command</li><li>Undo-able Clear, keyboard shortcuts, built-in help</li><li>Dark &amp; light themes, fully translated into 7 languages</li></ul>
<strong>Built-in redirect analysis — 9 local checks</strong>

Loops and ping-pong patterns, long chains, mixed 301/302 types, 4xx/5xx dead ends, OAuth/login bounces, locale/consent hops, tracking noise, CDN intermediaries (Cloudflare, CloudFront, Akamai, Fastly). Every issue gets a severity level, per-hop annotations with timings, and a copyable report.

<strong>Who it's for</strong>

SEO specialists auditing redirect chains and canonicalization; developers debugging navigation and client-side redirects (JSON and cURL export included); QA engineers verifying landing and login flows; affiliate managers checking cloaked links; anyone who wants to know where a link goes before clicking through.

<strong>Private by design</strong>

Everything runs locally. No accounts, no analytics, no telemetry, zero network requests by default. The manual URL check is an ordinary browser navigation in a background tab that closes itself.
