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

Guilhermefrj scores highly overall, with a thorough launch checklist, well-configured email security, and fast page loads. Main gaps: no Permissions-Policy, incomplete legal pages, and tracking cookies set before any opt-in.

Launched on Hacker News on July 4, 2026. The site is served through Cloudflare, with a domain registered in 1998. We've detected 14 technologies on this site, covering analytics, javascript library, security, and advertising. The stack includes Apollo Client, Apple App Store, and Cloudflare.

It's more locked down than the typical Hacker News launch.
