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 20 April 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.

FlashZen covers some of the launch checklist. Worth fixing first: missing several security headers, incomplete legal pages, and no sitemap.

Launched on Product Hunt on April 19, 2026. The site is hosted on Online SAS in France, with a domain registered in 2016. Our crawler found 7 technologies on this site, covering AI builders, analytics, CSS frameworks, and developer tools. The stack includes Tailwind CSS, Apache, and Debian.

It's also running the same core stack as 7,711 other launches.

This score is based on structural patterns and is not definitive. Many legitimate sites may trigger signals, and AI-built sites may go undetected. It should be treated as an indicator, not a verdict.
