About this list

The extension decides who can register the name and what it signals to a visitor. Domains here carry a link from Hacker News and sit on .io.

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.
