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

QR-Dragonfly has the basics covered well, with complete legal pages, a thorough launch checklist, and clean crawl signals. Main gaps: missing several security headers, tracking cookies set before any opt-in, and no email security records.

Launched on Product Hunt on June 15, 2026. The site is hosted on Amazon.com in the United States, with a domain registered 5 months before launch. Our crawler found 10 technologies on this site, covering analytics, build tooling, CDN, and cloud. The stack includes Vite, Vue.js, and Amazon Web Services.

Notably, it's the only launch we've crawled on this exact stack.
