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 25 June 2026; the live site may have changed since.
Excel spreadsheets to MARC21 Converter looks production-ready overall, with a thorough launch checklist and clean crawl signals. What needs work: missing several security headers, incomplete legal pages, and incomplete email security.
