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.
QR Master is largely in shape, with a thorough launch checklist and clean crawl signals. Main gaps: missing several security headers, incomplete legal pages, and incomplete email security.
Launched on Product Hunt on June 8, 2026. The site is hosted on Cloudflare in the United States, with a domain registered 6 months before launch. The crawl picked up 10 technologies on this site, covering transactional email, auth, CDN, and CSS frameworks. The stack includes Auth.js, React, and Tailwind CSS.
For context, it's on one of the most common stacks we track, shared by 176 launches.
