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 4 June 2026; the live site may have changed since.
Duckling ships with the launch fundamentals in place, with complete legal pages, a thorough launch checklist, and clean crawl signals. Worth fixing first: no Content-Security-Policy, analytics without a consent banner, and no email security records.
Launched on Product Hunt on June 4, 2026. The site is hosted on Cloudflare in the United States. Our crawler found 14 technologies on this site, covering advertising, analytics, security, and build tooling. The stack includes Tailwind CSS, Vite, and Cloudflare.
Notably, it's running the same core stack as 2,766 other launches and tighter on security headers than most Product Hunt launches.
