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 28 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.

CleanMySheet scores highly 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 Hacker News on August 28, 2026. The site is hosted on Vercel, with a domain registered 1 day before launch. Our crawler found 9 technologies on this site, covering analytics, CSS frameworks, DNS providers, and frameworks. The stack includes Next.js, React, and Tailwind CSS.

It's also on one of the most common stacks we track, shared by 14,367 launches.
