Reports, updated September 2026
- Website Platform ReportHow WordPress, Shopify, Next.js, Webflow and the rest compare on server response time, page weight, security headers and the search basics.
- Security Header AdoptionHow many sites send each of the six HTTP security headers, and what each one protects a visitor against.
How this was measured
Chckr requested the home page of the top 10,000 domains on the Tranco list (list N2PYW) once each on September 16, 2026, and read what came back. 5,827 of them returned a readable HTML home page; the rest were content delivery hosts, API endpoints, or servers that turn automated requests away.
Response time is the wait before the first byte of the reply arrives, measured from a single location, so it carries the distance between the test machine and the server. Platform is detected from markers in the page itself, which means a site behind a heavy proxy or a custom build can be counted as unnamed. Everything here describes home pages, not whole sites.
