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 4 July 2026; the live site may have changed since.

Solitaire.Free ships with the launch fundamentals in place, with complete legal pages, a thorough launch checklist, and well-configured email security. What needs work: missing several security headers.

Launched on Hacker News on July 3, 2026. The site is hosted on Cogent Communications in the United States, with a domain registered the day of launch. We've detected 7 technologies on this site, covering backend framework, CSS frameworks, DNS providers, and os. The stack includes Bootstrap, Django, and Google Search Console.

It's running the same core stack as 277 other launches.
