Own this Launch?

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 16 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.

White Screen Full Screen is partway there, with a thorough launch checklist and clean crawl signals. Main gaps: missing several security headers, incomplete legal pages, and tracking cookies set before any opt-in.

Launched on Product Hunt on June 16, 2026. The site is served through Cloudflare, with a domain registered 9 weeks before launch. The crawl picked up 15 technologies on this site, covering analytics, directory, CDN, and CSS frameworks. The stack includes Alpine.js, Tailwind CSS, and Cloudflare.

For context, it's on one of the most common stacks we track, shared by 215 launches.
