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

Clu3 ships with the launch fundamentals in place, with complete legal pages, a complete set of security headers, and a thorough launch checklist. What needs work: no email security records.

Launched on Product Hunt on June 10, 2026. The site is hosted on Amazon.com in the United States. The crawl picked up 17 technologies on this site, covering security, analytics, APIs, and auth. The stack includes Clerk, Google, and Next.js.

For context, it's running the same core stack as 7,154 other launches and tighter on security headers than most Product Hunt launches.

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.
