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 2 September 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.
SEOmatic for Claude & ChatGPT ships with the launch fundamentals in place, with complete legal pages, a thorough launch checklist, and clean crawl signals. Worth fixing first: no Content-Security-Policy, tracking cookies set before any opt-in, and incomplete email security.
Launched on Product Hunt on September 2, 2026. The site is hosted on Hetzner Online GmbH in Germany, with a domain registered in 2022. We've detected 16 technologies on this site, covering javascript library, affiliate, analytics, and chat widgets. The stack includes Next.js, React, and Tailwind CSS.
It's running the same core stack as 5,829 other launches and tighter on security headers than most Product Hunt launches.
