Extend.Domains Turns Domain Research Into a Sidebar

Field notes

The extension combines several public checks in a sidebar opened from a highlighted domain, including RDAP registration data, DNS-over-HTTPS records, parking-pattern matches, root-page metadata, and Wayback history. Its local quality score exposes component signals such as pronounceability, TLD, hyphens, and digits rather than presenting only a single unexplained number. Results are described as cached locally for 24 hours, while availability failures remain unknown instead of being treated as unregistered names.
