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 April 2026; the live site may have changed since.

GreenCube ships with the basics, with a thorough launch checklist, well-configured email security, and clean crawl signals. Worth fixing first: missing several security headers and incomplete legal pages.

Launched on Product Hunt on April 6, 2026. The site is hosted on Vercel, with a domain registered 1 week before launch. We've detected 6 technologies on this site, covering DNS providers, email forwarding, web fonts, and hosting. The stack includes Cloudflare DNS, Cloudflare Email Routing, and Google Fonts.

It's running the same core stack as 2,955 other launches.

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.
