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 9 July 2026; the live site may have changed since.
Sudoku Twist has the basics covered well, 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 July 9, 2026. The site is served through Fastly, with a domain registered 2 weeks before launch. Our crawler found 7 technologies on this site, covering CDN, DNS providers, business email, and javascript library. The stack includes Fastly, Google Play, and Google Search Console.
