Compare two URL behaviors side by side
Link Compare checks both URLs and shows whether they resolve to the same place, how their health scores differ, how many redirects and tracking parameters each contains, and whether their page fingerprints match.
How it helps
It is useful for before/after migrations, duplicate URL checks and verifying whether two campaign links eventually reach the same content.
How URLClinic approaches the check
URLClinic uses a Cloudflare Worker to request only public HTTP or HTTPS destinations. Redirects are followed manually so each hop can be validated and shown. Response content is size-limited, private network targets are blocked, and the tool avoids forwarding browser cookies or authentication headers to the destination.
The result is designed for practical decisions. It combines raw technical details with plain-language findings and links to related actions such as cleaning, recovery, Rescue Links, monitoring and QR generation.
Limitations you should know
Some websites block automated requests or serve different content to automated clients. A timeout or 403 therefore does not always mean a link is broken. URLClinic also does not execute a full browser session for every analysis, so JavaScript-only content may expose less metadata than a normal browser view.
