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 5 May 2026; the live site may have changed since.
Agentic API Grader by SaaStr.ai scores highly overall, with complete legal pages, a thorough launch checklist, and clean crawl signals. Visible gaps: no Permissions-Policy, tracking cookies set before any opt-in, and no email security records.
