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 1 September 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.

Door 24 scores highly overall, with complete legal pages, a thorough launch checklist, and clean crawl signals. Main gaps: missing Permissions-Policy and Content-Security-Policy and incomplete email security.

Launched on Product Hunt on September 1, 2026. The site is hosted on Vercel, with a domain registered in 2025. Our crawler found 13 technologies on this site, covering javascript library, analytics, baas, and CSS frameworks. The stack includes Next.js, React, and Tailwind CSS.

It's also on one of the most common stacks we track, shared by 14,763 launches and more locked down than the typical Product Hunt launch.
