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

VertexStellar is partway there, with a thorough launch checklist, fast page loads, and clean crawl signals. Visible gaps: missing several security headers, incomplete legal pages, and tracking cookies set before any opt-in.

Launched on Product Hunt on July 22, 2026. The site is served through Cloudflare. The crawl picked up 13 technologies on this site, covering analytics, seo, CDN, and developer tools. The stack includes CARTO, Cloudflare, and Cloudflare DNS.
