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 13 April 2026; the live site may have changed since.
Koalr scores highly overall, with complete legal pages, a complete set of security headers, and a thorough launch checklist. Main gaps: incomplete email security.
