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 22 August 2026; the live site may have changed since.
Numvax ships with the launch fundamentals in place, with complete legal pages, a thorough launch checklist, and clean crawl signals. What needs work: no Content-Security-Policy and incomplete email security.
Launched on Product Hunt on August 22, 2026. The site is hosted on Vercel, with a domain registered 1 week before launch. We've detected 13 technologies on this site, covering advertising, analytics, consent tooling, and CSS frameworks. The stack includes Google, Next.js, and React.
It's running the same core stack as 13,761 other launches and tighter on security headers than most Product Hunt launches.

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.
