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 11 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.

Vasulify covers some of the launch checklist, with a thorough launch checklist and clean crawl signals. What needs work: missing several security headers, incomplete legal pages, and incomplete email security.

Launched on Product Hunt on May 11, 2026. The site is hosted on Azure App Service, with a domain registered 1 day before launch. Our crawler found 11 technologies on this site, covering backend framework, CSS frameworks, DNS providers, and email forwarding. The stack includes Alpine.js, Tailwind CSS, and ASP.NET.

It's also running a stack combination we've seen on no other launch.
