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 27 April 2026; the live site may have changed since.
OpenQR — Free QR Code Generator has the basics covered well, with complete legal pages and clean crawl signals. Worth fixing first: missing several security headers and incomplete email security.
Launched on Product Hunt on April 27, 2026. The site is hosted on GitHub Pages and served through Cloudflare. Our crawler found 11 technologies on this site, covering CDN, baas, DNS providers, and email forwarding. The stack includes Brevo, cdnjs, and Cloudflare.
It's also running the same core stack as 1,757 other launches.
