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.

Cards AI looks production-ready overall, with complete legal pages, a thorough launch checklist, and clean crawl signals. Main gaps: missing several security headers, tracking cookies set before any opt-in, and no email security records.

Launched on Product Hunt on June 23, 2026. The site is hosted on Amazon.com in the United States, with a domain registered 9 weeks before launch. We've detected 16 technologies on this site, covering analytics, security, CDN, and CSS frameworks. The stack includes Next.js, React, and Tailwind CSS.

It's on one of the most common stacks we track, shared by 8,317 launches.
