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 10 August 2026; the live site may have changed since.

Gymcalc ships with the basics, with clean crawl signals. Visible gaps: missing several security headers, incomplete legal pages, and incomplete email security.

Launched on Hacker News on August 10, 2026. The site is hosted on Netlify, with a domain registered 7 months before launch. We've detected 6 technologies on this site, covering DNS providers, hosting, javascript library, and package cdn. The stack includes Emscripten, Google Search Console, and HSTS.

It's on one of the most common stacks we track, shared by 1,869 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.
