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 July 2026; the live site may have changed since.

CardMasters scores highly overall, with complete legal pages, a complete set of security headers, and a thorough launch checklist. Main gaps: no email security records.

Launched on Product Hunt on July 16, 2026. The site is hosted on Vercel, with a domain registered 5 weeks before launch. We've detected 10 technologies on this site, covering security, analytics, baas, and DNS providers. The stack includes Next.js, React, and Google Search Console.

It's on one of the most common stacks we track, shared by 2,296 launches and more locked down than the typical Product Hunt launch.
