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 16 June 2026; the live site may have changed since.
Real Fitness Calculator is largely in shape, with complete legal pages, a thorough launch checklist, and fast page loads. Visible gaps: missing several security headers, tracking cookies set before any opt-in, and incomplete email security.
Launched on Product Hunt on June 16, 2026. The site is hosted on Cloudflare in the United States, with a domain registered 1 week before launch. The crawl picked up 8 technologies on this site, covering analytics, CDN, DNS providers, and business email. The stack includes Astro, Cloudflare, and Cloudflare DNS.
For context, it's on one of the most common stacks we track, shared by 128 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.
