A signed protective layer for a destination
A Rescue Link creates a URLClinic address containing a cryptographically signed destination. When the link is used, URLClinic re-checks the destination. If auto-recovery was enabled and the page is unavailable, URLClinic can look for a high-confidence replacement on the same site before redirecting.
How it helps
The zero-config Rescue Link does not require an account or database and cannot be silently edited after creation. To point somewhere else, create a new Rescue Link. Direct redirects stay fast and there is no forced advertising interstitial.
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.
