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 8 August 2026; the live site may have changed since.
Sudoku AZ has the basics covered well, with a thorough launch checklist and clean crawl signals. Main gaps: missing several security headers, incomplete legal pages, and tracking cookies set before any opt-in.
