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 17 June 2026; the live site may have changed since.
Passlit Openbook is largely in shape, with a thorough launch checklist, well-configured email security, and clean crawl signals. Worth fixing first: missing several security headers, incomplete legal pages, and tracking cookies set before any opt-in.
Launched on Product Hunt on June 17, 2026. The site is hosted on Render in the United States, with a domain registered 4 weeks before launch. The crawl picked up 11 technologies on this site, covering AI builders, analytics, build tooling, and CDN. The stack includes Vite, Base44, and Cloudflare.
For context, it's one of 54 launches on this exact stack.

Vibe Score Breakdown How?

This score is based on structural patterns and is not definitive. Many legitimate sites may trigger signals, and AI-built sites may go undetected. It should be treated as an indicator, not a verdict.
