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 4 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.
Sink In covers some of the launch checklist, with a thorough launch checklist and fast page loads. Visible gaps: no Permissions-Policy, incomplete legal pages, and no robots.txt or sitemap.
Launched on Product Hunt on May 4, 2026. The site is hosted on HETZNER-AS in Germany, with a domain registered 8 months before launch. Our crawler found 8 technologies on this site, covering CSS frameworks, DNS providers, email forwarding, and frameworks. The stack includes Next.js, React, and Tailwind CSS.
It's also on one of the most common stacks we track, shared by 5,885 launches and more locked down than the typical Product Hunt launch.
