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

Corewar ships with the basics, with complete legal pages and fast page loads. Worth fixing first: missing several security headers, no robots.txt, and incomplete email security.

Launched on Hacker News on June 23, 2026. The site is hosted on Enix Ltd in the United Kingdom, with a domain registered in 2004. We've detected 6 technologies on this site, covering business email, DNS providers, protocol, and security. The stack includes Enmail, HostNS, and HostNS Email.

This score is based on structural patterns and is not definitive. Many legitimate sites may trigger signals, and AI-built sites may go undetected. It should be treated as an indicator, not a verdict.
