StackScope is a free public catalogue of indie launches. We find launches on Product Hunt, Hacker News and similar feeds, then crawl each site to detect its tech stack and score 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.

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 Amazon.com in the United States, with a domain registered in 2025. We've detected 15 technologies on this site, covering advertising, hosting, analytics, and build tooling. The stack includes Consentmanager, Tailwind CSS, and Vite.

It's the only launch we've crawled on this exact stack.
