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 28 August 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.

CalcBundle ships with the launch fundamentals in place, with complete legal pages, a complete set of security headers, and a thorough launch checklist. Worth fixing first: incomplete email security.

Launched on Product Hunt on August 28, 2026. The site is hosted on Hostinger, with a domain registered 6 days before launch. Our crawler found 10 technologies on this site, covering advertising, consent tooling, CSS frameworks, and DNS providers. The stack includes Google Funding Choices, Next.js, and React.

It's also running the same core stack as 388 other launches and tighter on security headers than most Product Hunt launches.
