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

DubDuck ships with the launch fundamentals in place, with complete legal pages, a thorough launch checklist, and fast page loads. Worth fixing first: missing several security headers and no email security records.

Launched on Product Hunt on June 16, 2026. The site is hosted on Amazon.com in the United States, with a domain registered 12 weeks before launch. The crawl picked up 9 technologies on this site, covering build tooling, CDN, CSS frameworks, and DNS providers. The stack includes Tailwind CSS, Vite, and Cloudflare.

For context, it's running the same core stack as 3,205 other launches.
