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 8 June 2026; the live site may have changed since.
QRFree has the basics covered well, with complete legal pages and a thorough launch checklist. Main gaps: missing several security headers, no robots.txt, and analytics without a consent banner.
Launched on Product Hunt on June 8, 2026. The site is hosted on Amazon.com in the United States. Our crawler found 10 technologies on this site, covering seo, analytics, CSS frameworks, and DNS providers. The stack includes Next.js, React, and Tailwind CSS.
Notably, it's on one of the most common stacks we track, shared by 7,370 launches.
