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 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.

Whosbuilt is missing several launch fundamentals. Visible gaps: missing several security headers, incomplete legal pages, and no mobile viewport meta tag.

Launched on Hacker News on July 4, 2026. The site is hosted on Hetzner Online GmbH in Germany, with a domain registered 11 weeks before launch. Our crawler found 3 technologies on this site, covering DNS providers, seo, and servers. The stack includes Caddy, Cloudflare DNS, and Google Search Console.
