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 15 June 2026; the live site may have changed since.

Grok 4 Free is partway there, with a thorough launch checklist, fast page loads, and clean crawl signals. Main gaps: missing several security headers, incomplete legal pages, and incomplete email security.

Launched on PeerPush on June 15, 2026. The site is hosted on Cloudflare in the United States, with a domain registered 11 months before launch. The crawl picked up 30 technologies on this site, covering directory, advertising, analytics, and CDN. The stack includes Google Funding Choices, Cloudflare, and Cloudflare DNS.
