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 13 July 2026; the live site may have changed since.

QR Kuz ships with the launch fundamentals in place, with complete legal pages, a thorough launch checklist, and fast page loads. Worth fixing first: missing several security headers and no email security records.

Launched on Product Hunt on July 13, 2026. The site is served through Cloudflare. We've detected 6 technologies on this site, covering CDN, CSS frameworks, DNS providers, and web fonts. The stack includes Tailwind CSS, Cloudflare, and Cloudflare DNS.

It's running the same core stack as 5,731 other launches.
