About this list
Narrowing a category to one extension is how a registrar choice or a market focus usually starts: the same topic reads differently on .com than elsewhere, and the extension decides who can register the name.
Every listing is verified the same way as the rest of the directory. Availability is re-checked against the live DNS root over DNS-over-HTTPS, and a listing that turns out to be registered is removed. Referring domains are counted from our own web crawl, not from a paid link index. Site history comes from archived captures: the archived snapshot count and the span of years the site was captured. Revised Score blends link-graph centrality, referring domains and site history into one 0 to 100 grade, computed across the whole directory.
