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 7 July 2026; the live site may have changed since.
Calculo looks production-ready overall, with complete legal pages, a thorough launch checklist, and well-configured email security. What needs work: missing several security headers.
