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 15 July 2026; the live site may have changed since.

Lab ships with the basics, with a complete set of security headers. What needs work: incomplete legal pages, no robots.txt or sitemap, and incomplete email security.

Launched on Hacker News on July 15, 2026. The site is served through AWS CloudFront, with a domain registered 1 week before launch. We've detected 7 technologies on this site, covering CDN, cloud, DNS providers, and javascript library. The stack includes Amazon Web Services, AWS CloudFront, and AWS Route 53.

It's tighter on security headers than most Hacker News 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.
