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 7 July 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.
Numberthon scores highly overall, with a thorough launch checklist and clean crawl signals. Visible gaps: no Content-Security-Policy, incomplete legal pages, and incomplete email security.
Launched on PeerPush on July 7, 2026. The site is hosted on Render and served through Cloudflare, with a domain registered 7 months before launch. We've detected 14 technologies on this site, covering javascript library, seo, ui library, and AI builders. The stack includes Tailwind CSS, Base44, and Bing Webmaster.
It's on one of the most common stacks we track, shared by 723 launches and more locked down than the typical PeerPush launch.
