Why the domain tools read the registry rather than a mirror
Most free domain tools go through their own server, which asks the registry or a WHOIS service on your behalf and may serve an answer it cached earlier. That is usually accurate and occasionally wrong in the direction that matters, showing a renewed domain as expiring or a lapsed one as safe.
These ask the registry operator directly over RDAP, the protocol registries are required to serve. The answer is the registry's own, and you can check any of it with whois on your own machine.
Watching, not just checking
A lookup is a snapshot. DropPerch re-reads the registry daily for every domain you watch and emails you before it expires — any registrar, no transfer, 25 domains free for the first 25 accounts, 5 after.
