Live trace
Watch redirect hops stream in as the page loads. Each hop carries status, method, protocol, timing, and full URL — so you see the chain in motion, not after the fact.
Chrome extension · v1.0
Where does this link
actually go?
Redirect Radar follows HTTP redirect chains hop-by-hop, grades security, and inspects URLs, headers and cookies — all from a Chrome popup. Trace data never leaves your browser.

Inside the popup
A complete redirect inspector, packed into a 640×520 popup.
Seven panels, one workflow. Open the popup on any tab to see what really happens between the click and the page.

URL Inspector
Pop any hop open and see protocol, host, port, path, and every query parameter parsed and decoded. UTM jungle, OAuth callbacks, tracker blobs — flat-listed.

Header inspection
A dark, terminal-style headers panel for every hop. Click any row to copy the key:value pair. Find Location, HSTS, CSP, Set-Cookie at a glance.
Cookie analyzer
Every Set-Cookie surfaced with Secure / HttpOnly / SameSite badges. Values are masked by default — click to reveal, with a warning.

Missing CSP
Security grade (A–F)
HSTS, mixed-content, downgrade hops, third-party cookies, and missing CSP each move the needle. A letter grade you can show a stakeholder.

Export anywhere
Copy a chain as cURL for your terminal, Markdown for a ticket, JSON for a script, or HAR for DevTools. Reproduce a redirect in two seconds.
Click → trace → fix
From toolbar click to fix-it copy in four steps.
- 01
Install in one click
Add Redirect Radar from the Chrome Web Store. No accounts, no subscription. Anonymous usage stats only — your URLs and headers stay on your device.
- 02
Open on any tab
Click the toolbar icon. Auto-trace runs as the page loads — or paste any URL into the bar to trace on demand.
- 03
Inspect the chain
Read every hop's status, headers, cookies and timing. Click a hop to expand. Switch to the Insights tab for security findings.
- 04
Export or fix
Copy as cURL, Markdown, JSON or HAR — share with a teammate or paste into a ticket. Each finding has a one-line fix.
In the wild
Built for anyone who’s ever cursed at 301 chains.
Debug OAuth and SSO flows
Why does the callback land on the wrong subdomain? See every redirect, every Set-Cookie, every state param — without piping logs through your terminal.
Reproduce flaky redirects
Capture a HAR, drop it in a Linear ticket, attach the cURL. The reproducer is one click away — no dev tools recording session needed.
Spot downgrades and tracker hops
See when an HTTPS link briefly drops to HTTP, which third-party trackers sit between the click and the destination, and which cookies follow you.
Audit affiliate and tracking links
Verify the deep link survives every click-tracker between the ad and the landing page. Catch stripped UTM params before they nuke your campaign reports.
Triage 'this link is broken' tickets
Paste the URL from the ticket. See whether it's a 410, a redirect loop, or a CDN cache miss — and drop the full trace straight into the reply.
Versus a web checker
Why Redirect Radar instead of a web checker?
Web-based redirect checkers re-fetch the URL from their own servers. That misses your cookies, your auth state, your country’s edge. DevTools sees everything but doesn’t score or export it.

From the field
What people say after a week of using it.
“I open it three times a day. The cURL export alone saved me from copy-pasting tcpdump into tickets.”
“The headers panel in dark mode is a small detail that turned this into a daily driver. Click-to-copy is chef's kiss.”
The fine print
Honest answers to the obvious questions.
Your URLs, headers and cookies stay on your device — trace data never leaves your browser. The extension does send anonymous usage stats (event names like popup_opened, tab_switched, export_used plus a per-install UUID) to Google Analytics 4 to help prioritise improvements. No URLs, headers, cookies or page content are ever transmitted.
