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 10 August 2026; the live site may have changed since.

ZenRockets looks production-ready overall, with complete legal pages, a thorough launch checklist, and clean crawl signals. Main gaps: missing several security headers and incomplete email security.

Launched on Product Hunt on August 10, 2026. The site is hosted on Railway and served through Cloudflare, with a domain registered 8 weeks before launch. We've detected 15 technologies on this site, covering javascript library, ui library, analytics, and CDN. The stack includes Tailwind CSS, TanStack Start, and Cloudflare.

It's one of just 9 launches we've crawled on this exact stack.

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.
