What websites are built with Ruby on Rails?

The full list is shown above. Each site was verified through multi-layer detection including HTTP response headers, HTML content analysis, DNS record lookups, and TLS certificate inspection.

How do you detect Ruby on Rails on a website?

DetectZeStack uses four detection methods that work together: HTTP header fingerprinting, HTML/JavaScript pattern matching, DNS CNAME and TXT record analysis, and TLS certificate inspection. This catches technologies that browser-only tools like WhatRuns or Wappalyzer miss entirely.
