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

CalcTap ships with the launch fundamentals in place, with complete legal pages, a thorough launch checklist, and clean crawl signals. Worth fixing first: missing Permissions-Policy and Strict-Transport-Security and incomplete email security.

Launched on Product Hunt on June 23, 2026. The site is hosted on Hostinger International Limited in Germany, with a domain registered 3 months before launch. The crawl picked up 8 technologies on this site, covering servers, analytics, backend framework, and business email. The stack includes Google Analytics, Google Fonts, and Hostinger.

For context, it's running the same core stack as 673 other launches and tighter on security headers than most Product Hunt launches.
