Extend.Domains Turns a Highlighted Domain Into a Research Panel

extend.domains Observed source

Editorial interest 84/100 Selection signal · not a rating of the site

A free, open-source browser extension that checks registration, DNS, parking, site metadata, archive history, and a local quality score for any domain you highlight.

Landing page captured for the 2026-09-06 issue.

Field notes

The extension separates its lookup into independent cards for registry data, DNS, parking status, page metadata, archive history, and local scoring, so one failed source does not remove the others. Its score exposes a per-component breakdown rather than returning a single unexplained number. The page also specifies a 32 KB limit for root-page metadata and a 24-hour local cache, with data gathered from public endpoints and no stated backend, account, API key, or analytics.
