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 August 2026; the live site may have changed since.
CloserGym ships with the launch fundamentals in place, with complete legal pages, a complete set of security headers, and a thorough launch checklist. Worth fixing first: incomplete email security.
Launched on Product Hunt on August 21, 2026. The site is hosted on Railway, with a domain registered 5 months before launch. The crawl picked up 25 technologies on this site, covering auth, payments, ai api, and analytics. The stack includes Google Identity Platform, Google Sign-In, and Tailwind CSS.
For context, it's running the same core stack as 329 other launches and tighter on security headers than most Product Hunt 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.
