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 26 August 2026; the live site may have changed since.
Calvras looks production-ready overall, with complete legal pages, a thorough launch checklist, and fast page loads. Main gaps: missing several security headers and no email security records.
