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 19 April 2026; the live site may have changed since.
CaptainDNS ships with the launch fundamentals in place, with complete legal pages, a complete set of security headers, and a thorough launch checklist.
Launched on Product Hunt on April 18, 2026. The site is hosted on Vercel, with a domain registered 7 months before launch. We've detected 13 technologies on this site, covering payments, APIs, CSS frameworks, and DNS providers. The stack includes Next.js, React, and Tailwind CSS.
It's running the same core stack as 10,676 other launches and tighter on security headers than most Product Hunt launches.
