FAQ
How does it figure out what a site is built with?
It inspects passive signals - HTTP response headers, cookies, HTML markup, script paths, and loaded resources, and matches them against a library of technology signatures, reporting a confidence level for each match.
Which CMS platforms can it detect?
WordPress, Shopify, Drupal, Joomla, Ghost, BigCommerce, OpenCart and many more, plus front-end frameworks (React, Vue, Angular, Next.js) and back-end stacks (PHP, Node.js, ASP.NET, Django, Rails, Laravel…).
Is it accurate?
Sites can hide or spoof some signals, so treat low-confidence results as hints. High and very-high confidence findings are backed by strong, hard-to-fake evidence like specific headers or framework fingerprints.
