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.

nyt sudoku looks production-ready overall, with complete legal pages, a thorough launch checklist, and clean crawl signals. Worth fixing first: 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 States, with a domain registered 5 months before launch. We've detected 8 technologies on this site, covering CDN, CSS frameworks, DNS providers, and business email. The stack includes Next.js, React, and Tailwind CSS.

It's running the same core stack as 2,519 other launches.
