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

Dataguessr scores highly overall, with a thorough launch checklist, fast page loads, and clean crawl signals. Visible gaps: no Permissions-Policy, incomplete legal pages, and incomplete email security.

Launched on Product Hunt on August 26, 2026. The site is served through Cloudflare, with a domain registered 12 months before launch. We've detected 12 technologies on this site, covering security, analytics, baas, and CDN. The stack includes Cloudflare, Cloudflare Bot Management, and Cyon DNS.

It's more locked down than the typical Product Hunt launch.
