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 17 June 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.

PCalen has the basics covered well, with complete legal pages, a thorough launch checklist, and well-configured email security. What needs work: missing several security headers and tracking cookies set before any opt-in.

Launched on Product Hunt on June 17, 2026. The site is served through Cloudflare, with a domain registered 7 weeks before launch. Our crawler found 16 technologies on this site, covering analytics, advertising, CDN, and CSS frameworks. The stack includes Nuxt, Tailwind CSS, and Vue.js.

It's also running the same core stack as 288 other launches.
