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.

Preloop looks production-ready overall, with complete legal pages, a thorough launch checklist, and fast page loads. Visible gaps: missing several security headers and incomplete email security.

Launched on PeerPush on September 2, 2026. The site is hosted on Hetzner Online GmbH in Germany, with a domain registered in 2025. We've detected 10 technologies on this site, covering analytics, developer tools, DNS providers, and business email. The stack includes Brevo, Google Domains DNS, and Google Search Console.

This score is based on structural patterns and is not definitive. Many legitimate sites may trigger signals, and AI-built sites may go undetected. It should be treated as an indicator, not a verdict.
