Canonical drift
Check whether the redirect path still lands on the intended final URL.
Documentation
Redirect Diff documentation
Compare two redirect chains with normalized hop diffs, final destination checks, and launch-ready change tracking.
Overview
Use it when the format needs to change, not the meaning
Use Redirect Diff when you want to compare the hop sequence for two public URLs before launch.
Host changes
Spot when a redirect chain crosses between hosts or schemes.
Launch QA
Review redirect changes before a site goes live.
Supported inputs
Bring clean source text and keep the direction straight
- Accepts two public URLs for redirect-chain inspection.
- Accept-Language can be overridden when redirect checks need a specific request header.
- Hop summaries help you compare the final destinations and response statuses.
Walk through it
Follow the same sequence you see in the tool
Workflow
Compare redirect chains
Use this flow when you want to compare the hop sequence for two public URLs.
- Enter the left and right URLs you want to compare.
- Adjust the optional Accept-Language header if the site varies by locale.
- Compare the final destinations, hop counts, and normalized chain diff.
Workflow
Review the final hop
Use this flow when the destination or status code changed and you need a quick review.
- Check the final URL values for host or scheme drift.
- Confirm the final response status for both chains.
- Copy the diff output into your release notes or QA checklist.
What you get
Check the result before you copy it into the next step
Hop-by-hop redirect diff
Redirect chains are normalized into comparable hop lines.
Final destination summary
Final URL, status, and host changes help you spot drift quickly.
Copy-ready diff
A normalized patch is available when you need to share the result.
Avoid these mistakes
Small input problems create the biggest conversion errors
Testing private URLs
Use public URLs for redirect inspection so the server can fetch them safely.
Ignoring the final hop
Always confirm the final URL and response status, not just the first redirect.
Skipping locale checks
Use Accept-Language when redirects vary by language or region.
Glossary
Decode the terms before you act on them
This section translates the most technical labels on the page into plain language so you can interpret the output without opening another tab.
Redirect hop
A redirect hop is one step in the chain from the starting URL to the final destination.
Final URL
The final URL is the last destination reached after the redirect chain finishes.
Scheme drift
Scheme drift means the chain changes between protocols such as HTTP and HTTPS.
Host drift
Host drift means the chain ends on a different hostname than the one you expected.
Normalized diff
A normalized diff compares the important redirect-chain details in a stable format so differences are easier to review.
