Own this Launch?

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 15 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.

BottleneckCalcs is partway there, with a thorough launch checklist and clean crawl signals. Worth fixing first: missing several security headers, incomplete legal pages, and tracking cookies set before any opt-in.

Launched on Product Hunt on May 15, 2026. The site is hosted on Vercel, with a domain registered 2 weeks before launch. The crawl picked up 13 technologies on this site, covering analytics, seo, CSS frameworks, and DNS providers. The stack includes Next.js, React, and Tailwind CSS.
