Redirect Inspector — Link & Redirect Checker wót 301.st

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.

Why Redirect Inspector

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

Built-in redirect analysis — 9 local checks

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.

Who it's for

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.

Private by design

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. Optional 301.sh news notifications are strictly opt-in and only fetch the public article feed.
