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 May 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.

ChalkLab covers some of the launch checklist, with a thorough launch checklist and clean crawl signals. Worth fixing first: missing several security headers, incomplete legal pages, and tracking cookies set before any opt-in.

Launched on PeerPush on May 2, 2026. The site is hosted on Vercel and served through Cloudflare, with a domain registered 4 months before launch. Our crawler found 21 technologies on this site, covering analytics, seo, advertising, and baas. The stack includes Next.js, React, and Tailwind CSS.

It's also running the same core stack as 15,030 other launches.
