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 3 July 2026; the live site may have changed since.
Postcard Pigeon looks production-ready overall, with complete legal pages, a thorough launch checklist, and well-configured email security. Main gaps: missing several security headers and tracking cookies set before any opt-in.

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.
