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 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.
ColorUI scores highly overall, with complete legal pages, a complete set of security headers, and a thorough launch checklist. Visible gaps: tracking cookies set before any opt-in and incomplete email security.
Launched on Product Hunt on May 1, 2026. The site is hosted on Hostinger. We've detected 14 technologies on this site, covering analytics, seo, advertising, and CSS frameworks. The stack includes React, Tailwind CSS, and Bing Webmaster.
It's one of just 18 launches we've crawled on this exact stack and more locked down than the typical Product Hunt launch.

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.
