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 26 May 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.

DiplomaCraft GPA Calculator scores highly overall, with complete legal pages, a thorough launch checklist, and well-configured email security. Main gaps: missing several security headers.

Launched on Product Hunt on May 26, 2026. The site is served through Cloudflare, with a domain registered 12 weeks before launch. We've detected 14 technologies on this site, covering analytics, business email, CDN, and chat widgets. The stack includes Nuxt, Tailwind CSS, and Vue.js.

It's on one of the most common stacks we track, shared by 289 launches.
