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

Sourcelibrary ships with the launch fundamentals in place, with complete legal pages, a complete set of security headers, and a thorough launch checklist.

Launched on Hacker News on June 7, 2026. The site is hosted on Cloudflare in the United States. The crawl picked up 22 technologies on this site, covering ai api, hosting, advertising, and auth. The stack includes Auth.js, Next.js, and React.

For context, it's on a stack we've seen on only 22 launches and tighter on security headers than most Hacker News launches.

This score is based on structural patterns and is not definitive. Many legitimate sites may trigger signals, and AI-built sites may go undetected. It should be treated as an indicator, not a verdict.
