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.
Certleaf has the basics covered well, 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 Hacker News on July 6, 2026. The site is served through Cloudflare, with a domain registered 1 week before launch. Our crawler found 14 technologies on this site, covering analytics, ui library, CDN, and CSS frameworks. The stack includes Tailwind CSS, TanStack Start, and Ahrefs.
It's also running the same core stack as 193 other 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.
