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 20 August 2026; the live site may have changed since.
PolyglotGym has the basics covered well, with a thorough launch checklist, well-configured email security, and clean crawl signals. Worth fixing first: missing Permissions-Policy and Content-Security-Policy and incomplete legal pages.
Launched on Product Hunt on August 20, 2026. The site is served through Cloudflare, with a domain registered 5 months before launch. Our crawler found 14 technologies on this site, covering analytics, seo, CDN, and consent tooling. The stack includes Google, Next.js, and React.
It's also running the same core stack as 5,206 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.
