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 27 June 2026; the live site may have changed since.

Stamina covers some of the launch checklist, with a thorough launch checklist, well-configured email security, and fast page loads. Worth fixing first: missing several security headers and incomplete legal pages.

Launched on Product Hunt on June 27, 2026. The site is hosted on Amazon.com in the Netherlands. Our crawler found 11 technologies on this site, covering javascript library, AI builders, crm, and DNS providers. The stack includes Clay, Close, and Cloudflare DNS.

SignalPoints
Recognised AI builder signature +100

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.
