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

Master Chess ships with the launch fundamentals in place, with complete legal pages, a thorough launch checklist, and clean crawl signals. What needs work: missing several security headers and incomplete email security.

Launched on Product Hunt on June 8, 2026. The site is hosted on Cloudflare in the United Arab Emirates, with a domain registered 10 weeks before launch. The crawl picked up 10 technologies on this site, covering security, AI builders, build tooling, and CDN. The stack includes Tailwind CSS, Vite, and Cloudflare.

For context, it's running the same core stack as 3,110 other launches.
