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

GN PDF scores well across the board, with complete legal pages, a thorough launch checklist, and clean crawl signals. Visible gaps: no Strict-Transport-Security, tracking cookies set before any opt-in, and incomplete email security.

Launched on Product Hunt on June 28, 2026. The site is hosted on Hostinger International Limited in the United States, with a domain registered 8 months before launch. The crawl picked up 12 technologies on this site, covering package cdn, servers, analytics, and developer tools. The stack includes cdnjs, Google Analytics, and Google Fonts.

For context, it's on one of the most common stacks we track, shared by 714 launches and more locked down than the typical Product Hunt launch.
