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 14 April 2026; the live site may have changed since.
Marinecharts scores highly overall, with complete legal pages and clean crawl signals. Visible gaps: missing Permissions-Policy and Strict-Transport-Security and no email security records.
Launched on Hacker News on April 14, 2026. The site is hosted on Fly.io and served through Cloudflare. Our crawler found 9 technologies on this site, covering analytics, CDN, CSS frameworks, and DNS providers. The stack includes Tailwind CSS, Cloudflare, and Cloudflare DNS.
It's also one of 62 launches 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.
