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

Redflag-check is partway there, with fast page loads and clean crawl signals. Visible gaps: missing several security headers, incomplete legal pages, and incomplete email security.

Launched on Hacker News on June 11, 2026. The site is hosted on Amazon.com in the United States. The crawl picked up 4 technologies on this site, covering DNS providers, business email, hosting, and security. The stack includes HSTS, Namecheap DNS, and Namecheap Email Forwarding.

For context, it's on one of the most common stacks we track, shared by 1,283 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.
