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 9 August 2026; the live site may have changed since.

Violin-fingering covers some of the launch checklist, with a thorough launch checklist. Visible gaps: missing several security headers, incomplete legal pages, and no sitemap.
