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 11 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.
Clausign scores highly overall, with complete legal pages, a complete set of security headers, and a thorough launch checklist. Main gaps: tracking cookies set before any opt-in and incomplete email security.
Launched on Product Hunt on June 11, 2026. The site is served through AWS CloudFront, with a domain registered 6 weeks before launch. Our crawler found 18 technologies on this site, covering analytics, CDN, security, and cloud. The stack includes Next.js, React, and Tailwind CSS.
