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 4 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.

Universal Excel AI ships with the basics, with clean crawl signals. What needs work: missing several security headers, incomplete legal pages, and no email security records.

Launched on Product Hunt on June 4, 2026. The site is hosted on Vercel. We've detected 9 technologies on this site, covering analytics, baas, CSS frameworks, and DNS providers. The stack includes Tailwind CSS, cdnjs, and Firebase.

It's running the same core stack as 3,366 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.
