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

Calcula Zen covers some of the launch checklist, with a thorough launch checklist and clean crawl signals. Visible gaps: missing several security headers, incomplete legal pages, and incomplete email security.

Launched on Product Hunt on June 18, 2026. The site is hosted on Hostinger International Limited in Germany, with a domain registered 5 weeks before launch. Our crawler found 9 technologies on this site, covering analytics, CMS, consent tooling, and business email. The stack includes CookieYes, WordPress, and Elementor.

Notably, it's on one of the most common stacks we track, shared by 687 launches.

This score is based on structural patterns and is not definitive. Many legitimate sites may trigger signals, and AI-built sites may go undetected. It should be treated as an indicator, not a verdict.
