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

Yarrow Yi looks production-ready overall, with complete legal pages, a thorough launch checklist, and clean crawl signals. What needs work: missing several security headers and no email security records.

Launched on Product Hunt on June 9, 2026. The site is hosted on Cloudflare in the United States, with a domain registered 2 weeks before launch. We've detected 10 technologies on this site, covering CDN, DNS providers, business email, and transactional email. The stack includes Next.js, React, and Cloudflare.

It's one of 41 launches on this exact stack.

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.
