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 April 2026; the live site may have changed since.

Dualhook looks production-ready overall, with a thorough launch checklist and clean crawl signals. Visible gaps: missing several security headers, incomplete legal pages, and incomplete email security.

Launched on Hacker News on April 2, 2026. The site is hosted on Hostinger, with a domain registered 9 weeks before launch. We've detected 12 technologies on this site, covering hosting, analytics, auth, and CSS frameworks. The stack includes Clerk, Next.js, and React.

It's on one of the most common stacks we track, shared by 361 launches.
