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.
Purrlearn is largely in shape, with complete legal pages, a thorough launch checklist, and clean crawl signals. Worth fixing first: missing several security headers and incomplete email security.
Launched on Hacker News on July 5, 2026. The site is hosted on Render and served through Cloudflare, with a domain registered 2 weeks before launch. The crawl picked up 10 technologies on this site, covering auth, CDN, CSS frameworks, and DNS providers. The stack includes Auth.js, Next.js, and React.
For context, it's running the same core stack as 109 other 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.
