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 6 June 2026; the live site may have changed since.

CalculatorCove looks production-ready overall, with complete legal pages, a thorough launch checklist, and clean crawl signals. Worth fixing first: missing several security headers, analytics without a consent banner, and incomplete email security.

Launched on Product Hunt on June 6, 2026. The site is hosted on Hostinger International Limited in the United Kingdom, with a domain registered 3 months before launch. We've detected 5 technologies on this site, covering analytics, hosting, protocol, and seo. The stack includes Google Analytics, Google Search Console, and Hostinger.

It's running the same core stack as 487 other launches.
