Own this Launch?

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 30 April 2026; the live site may have changed since.

QR Tiger looks production-ready overall, with complete legal pages, a thorough launch checklist, and clean crawl signals. What needs work: missing several security headers, tracking cookies set before any opt-in, and no email security records.

Launched on Product Hunt on April 30, 2026. The site is hosted on Vercel, with a domain registered in 2019. We've detected 15 technologies on this site, covering security, analytics, chat widgets, and CSS frameworks. The stack includes Bootstrap, Next.js, and React.

It's on a stack we've seen on only 4 launches.
