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 3 August 2026; the live site may have changed since.
Seiri scores highly overall, with complete legal pages, a thorough launch checklist, and well-configured email security. Main gaps: missing several security headers and tracking cookies set before any opt-in.
