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 9 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.
Math Builders is largely in shape, with complete legal pages, a thorough launch checklist, and clean crawl signals. What needs work: missing several security headers, tracking cookies set before any opt-in, and incomplete email security.
Launched on Product Hunt on June 9, 2026. The site is served through Fastly, with a domain registered in 1998. The crawl picked up 10 technologies on this site, covering analytics, baas, CDN, and developer tools. The stack includes Contentsquare, Fastly, and Firebase.
