Website Tech & Domain Checker: See what any website is built with, plus its domain info

Hi Product Hunt! I'm Bion from Visigraphic, a small Drupal studio in Surabaya, Indonesia. When we take on a website project, the first questions are always the same: what is the site built with, and who controls the domain? Clients often can't answer either, and finding out means juggling several tools or asking a developer. So we put both lookups in one free page. Enter any website address and you'll see its CMS (with version when detectable), JavaScript libraries, web server, CDN and analytics, plus HTTPS, HSTS and mobile-readiness. The Domain & Whois side tells you whether a domain is available, who the registrar is, when it expires, and where its DNS points. No sign-up. We only read public information, and technology detection is an estimate, so some things may be missed. What would you want it to detect next?
