FAQ

What is a website built with?
Open the site's page (/tech-stack/site/<domain>) to see its CMS, JavaScript framework, CDN, hosting, analytics and other technologies, detected from the home page HTML and HTTP headers.
How are the technologies detected?
We fetch the home page once and match the HTML, script URLs, meta tags, cookies and response headers against a hand-written fingerprint list (the same engine as our Tech Stack Detector API). Technologies that leave no trace in the home page cannot be detected.
Which sites are in the index?
About 1,005 popular websites, the same sample as the AI Crawler Index (Tranco list, filtered). 748 had a readable home page with at least one detected technology.
