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 12 August 2026; the live site may have changed since.

YUESHAN PCB is largely in shape, with a thorough launch checklist and clean crawl signals. Visible gaps: missing several security headers, incomplete legal pages, and incomplete email security.

Launched on Product Hunt on August 12, 2026. The site is hosted on Alibaba (US) Technology Co. in Singapore, with a domain registered in 2018. The crawl picked up 4 technologies on this site, covering backend framework, DNS providers, business email, and servers. The stack includes Alibaba Cloud, Alibaba Mail, and ASP.NET.
