Screenshot of Shelf

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.

Shelf covers some of the launch checklist, with a thorough launch checklist and clean crawl signals. What needs work: missing several security headers, incomplete legal pages, and no email security records.

Launched on Product Hunt on June 27, 2026. The site is hosted on Amazon.com in the Netherlands, with a domain registered in 2018. Our crawler found 4 technologies on this site, covering AI builders, javascript library, protocol, and security. The stack includes Framer, HSTS, and HTTP/3.

SignalPoints

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.
