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

Chess Notate scores well across the board, with complete legal pages, a thorough launch checklist, and clean crawl signals. Main gaps: missing several security headers, analytics without a consent banner, and incomplete email security.

Launched on Product Hunt on June 12, 2026. The site is hosted on Amazon.com in the United States, with a domain registered 5 weeks before launch. The crawl picked up 10 technologies on this site, covering seo, analytics, baas, and DNS providers. The stack includes Next.js, React, and Bing Webmaster.

For context, it's one of 44 launches on this exact stack.
