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

FreeFlipbook is largely in shape, with complete legal pages, a thorough launch checklist, and clean crawl signals. What needs work: missing several security headers, tracking cookies set before any opt-in, and incomplete email security.

Launched on PeerPush on July 6, 2026. The site is served through Cloudflare, with a domain registered in 2025. The crawl picked up 15 technologies on this site, covering analytics, auth, CDN, and CSS frameworks. The stack includes Auth.js, Next.js, and React.

For context, it's running the same core stack as 3,358 other launches.
