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 April 2026; the live site may have changed since.

AgentGrade is partway there, with clean crawl signals. What needs work: missing several security headers, incomplete legal pages, and no email security records.

Launched on Hacker News on April 19, 2026. The site is hosted on BI-631 - Build io in the United States, with a domain registered in 2004. The crawl picked up 4 technologies on this site, covering developer tools, DNS providers, frameworks, and proxy. The stack includes Express, DNSimple, and Envoy.

For context, it's running the same core stack as 116 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.
