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 3 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.

Stefan covers some of the launch checklist, with a thorough launch checklist, fast page loads, and clean crawl signals. Worth fixing first: missing several security headers, incomplete legal pages, and incomplete email security.

Launched on Hacker News on May 3, 2026. The site is hosted on GitHub Pages and served through Fastly, with a domain registered in 1998. Our crawler found 2 technologies on this site, covering CDN and hosting. The stack includes Fastly and GitHub Pages.

It's also running the same core stack as 2,669 other launches.
