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 20 July 2026; the live site may have changed since.

BrowSync is early-stage. Main gaps: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.
