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

Simlink is largely in shape, with a thorough launch checklist, well-configured email security, and clean crawl signals. Main gaps: missing Permissions-Policy and Content-Security-Policy and incomplete legal pages.

Launched on Hacker News on June 19, 2026. The site is hosted on Cloudflare in the United States, with a domain registered 5 months before launch. The crawl picked up 8 technologies on this site, covering analytics, build tooling, CDN, and web fonts. The stack includes Rails, Vite, and Cloudflare.

For context, it's one of just 15 launches we've crawled on this exact stack and more locked down than the typical Hacker News launch.

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.
