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 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.
ClassKeep scores highly overall, with complete legal pages, a thorough launch checklist, and clean crawl signals. Visible gaps: missing Permissions-Policy and Content-Security-Policy and incomplete email security.
Launched on Hacker News on May 19, 2026. The site is hosted on Contabo in Germany, with a domain registered 8 weeks before launch. Our crawler found 10 technologies on this site, covering CSS frameworks, DNS providers, business email, and email forwarding. The stack includes Next.js, React, and Tailwind CSS.
It's also on one of the most common stacks we track, shared by 5,772 launches and more locked down than the typical Hacker News launch.
