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 13 April 2026; the live site may have changed since.
Yizhan is largely in shape, with complete legal pages, a thorough launch checklist, and clean crawl signals. Visible gaps: missing several security headers, tracking cookies set before any opt-in, and incomplete email security.
Launched on Product Hunt on April 13, 2026. The site is hosted on Vercel, with a domain registered in 2020. The crawl picked up 10 technologies on this site, covering analytics, auth, CSS frameworks, and DNS providers. The stack includes Auth.js, Next.js, and React.
For context, it's on one of the most common stacks we track, shared by 10,672 launches.
