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 23 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.

PaperGrader ships with the launch fundamentals in place, with complete legal pages, a thorough launch checklist, and well-configured email security. What needs work: missing several security headers.

Launched on Product Hunt on May 23, 2026. The site is served through Fastly, with a domain registered 11 weeks before launch. Our crawler found 10 technologies on this site, covering CDN, CSS frameworks, DNS providers, and business email. The stack includes Tailwind CSS, Fastly, and GoDaddy DNS.
