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 29 June 2026; the live site may have changed since.
QRGen is largely in shape, 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 incomplete email security.
Launched on Product Hunt on June 29, 2026. The site is hosted on Vercel and served through Cloudflare, with a domain registered 4 months before launch. The crawl picked up 13 technologies on this site, covering analytics, auth, CDN, and CSS frameworks. The stack includes Auth.js, Next.js, and React.
For context, it's on one of the most common stacks we track, shared by 8,807 launches.
