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 10 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.

Coolors looks production-ready overall, with a thorough launch checklist, fast page loads, and clean crawl signals. Main gaps: missing several security headers, incomplete legal pages, and incomplete email security.

Launched on Product Hunt on June 10, 2026. The site is hosted on AWS ALB, with a domain registered in 2025. We've detected 15 technologies on this site, covering advertising, hosting, analytics, and consent tooling. The stack includes Consentmanager, Tailwind CSS, and AWS ALB.

It's one of just 5 launches we've crawled on this exact stack.
