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 27 July 2026; the live site may have changed since.

WOW Sleep Calculator looks production-ready overall, with complete legal pages, a thorough launch checklist, and clean crawl signals. Visible gaps: missing several security headers and no email security records.

Launched on Product Hunt on July 27, 2026. The site is hosted on Amazon.com in the United States, with a domain registered 2 weeks before launch. We've detected 12 technologies on this site, covering ui library, AI builders, CSS frameworks, and developer tools. The stack includes Tailwind CSS, TanStack Start, and Caddy.

It's on one of the most common stacks we track, shared by 585 launches.
