Every site we track, and how it did
Each site below is checked against the Web 1.0 Specification (2026 Edition) roughly every two weeks: front page only, no scripts, no third parties, no cookies, no bloat. Click a site for its full report and history. The list covers the web's most-visited domains, a commended list of well-made sites, and submitted sites. We respect robots.txt: a site whose robots.txt refuses our checker is recorded as declined and does not pass.
Currently passing: 19 of 533 checked sites.
