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

CardAuthentico scores well across the board, with complete legal pages, a complete set of security headers, and a thorough launch checklist. Main gaps: incomplete email security.

Launched on PeerPush on June 23, 2026. The site is hosted on Amazon.com in the United States, with a domain registered in 2024. Our crawler found 46 technologies on this site, covering directory, analytics, javascript library, and payments. The stack includes eBay, Next.js, and React.

Notably, it's one of only 2 launches we've crawled running eBay and more locked down than the typical PeerPush launch.
