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 31 August 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.

Sunday Club ships with the launch fundamentals in place, with complete legal pages, a complete set of security headers, and a thorough launch checklist. Worth fixing first: incomplete email security.

Launched on Product Hunt on August 31, 2026. The site is hosted on Vercel, with a domain registered 1 week before launch. Our crawler found 15 technologies on this site, covering javascript library, analytics, CSS frameworks, and DNS providers. The stack includes Next.js, React, and Tailwind CSS.

It's also running the same core stack as 14,614 other launches and tighter on security headers than most Product Hunt launches.

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.
