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 21 April 2026; the live site may have changed since.
CalcHub ships with the launch fundamentals in place, with complete legal pages, a thorough launch checklist, and clean crawl signals. What needs work: missing several security headers and incomplete email security.
Launched on Product Hunt on April 21, 2026. The site is served through Cloudflare. Our crawler found 16 technologies on this site, covering advertising, security, AI builders, and CDN. The stack includes CookieYes, Tailwind CSS, and Cloudflare.
It's also running the same core stack as 5,948 other 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.
