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 17 June 2026; the live site may have changed since.
CastReader — AI Explain scores well across the board, with complete legal pages, a thorough launch checklist, and clean crawl signals. Main gaps: no Content-Security-Policy and incomplete email security.
Launched on Product Hunt on June 17, 2026. The site is hosted on Amazon.com in the United States, with a domain registered 7 months before launch. The crawl picked up 22 technologies on this site, covering directory, collaboration, CSS frameworks, and DNS providers. The stack includes Next.js, React, and Tailwind CSS.
For context, it's on one of the most common stacks we track, shared by 7,861 launches and more locked down than the typical Product Hunt launch.
