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

Classario scores well across the board, with complete legal pages, a thorough launch checklist, and fast page loads. Main gaps: missing several security headers, tracking cookies set before any opt-in, and incomplete email security.

Launched on Product Hunt on June 24, 2026. The site is hosted on Amazon.com in the Netherlands, with a domain registered in 2023. Our crawler found 17 technologies on this site, covering javascript library, analytics, advertising, and AI builders. The stack includes DOMPurify, Facebook Domain Verification, and Facebook Pixel.
