Screenshot of Quizingo

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

Quizingo ships with the launch fundamentals in place, with complete legal pages, a thorough launch checklist, and fast page loads. Worth fixing first: missing Permissions-Policy and Content-Security-Policy, tracking cookies set before any opt-in, and incomplete email security.

Launched on Hacker News on June 27, 2026. The site is hosted on Amazon.com in the United States, with a domain registered 9 months before launch. We've detected 9 technologies on this site, covering analytics, CSS frameworks, DNS providers, and email forwarding. The stack includes Next.js, React, and Tailwind CSS.

It's running the same core stack as 8,685 other launches and tighter on security headers than most Hacker News launches.
