StackScope records what new websites are built with, the week they launch. Most we find ourselves, by watching public internet infrastructure for brand-new sites; the rest come from Product Hunt, Hacker News and PeerPush. We crawled this one for its tech stack and scored it for launch readiness: DNS, security headers, SEO basics. This page is what we saw on 19 June 2026; the live site may have changed since.
Every technology below links to its own page: which other new sites launched with it. Vendors and agencies watch those pages with Stackdar and hear about new adopters the week they ship, from £15 a month.
HVAC system design course has the basics covered well, with clean crawl signals. What needs work: missing Permissions-Policy and Strict-Transport-Security, incomplete legal pages, and tracking cookies set before any opt-in.
Launched on Product Hunt on June 19, 2026. The site is hosted on Hostinger and served through Cloudflare. Our crawler found 13 technologies on this site, covering analytics, CDN, chat widgets, and DNS providers. The stack includes cdnjs, Cloudflare, and Font Awesome.
It's also running the same core stack as 1,294 other launches and tighter on security headers than most Product Hunt launches.
