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

LinkClass is largely in shape, with a thorough launch checklist, fast page loads, and clean crawl signals. Worth fixing first: missing several security headers, incomplete legal pages, and incomplete email security.

Launched on Product Hunt on June 6, 2026. The site is hosted on Cloudflare in the United States. The crawl picked up 8 technologies on this site, covering build tooling, CDN, CSS frameworks, and DNS providers. The stack includes Tailwind CSS, Vite, and Cloudflare.

For context, it's running the same core stack as 2,854 other 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.
