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 16 June 2026; the live site may have changed since.
PostcardTree has the basics covered well, with a thorough launch checklist and clean crawl signals. What needs work: missing several security headers, incomplete legal pages, and incomplete email security.
Launched on PeerPush on June 16, 2026. The site is hosted on Cloudflare in the United Arab Emirates, with a domain registered in 2015. Our crawler found 13 technologies on this site, covering security, AI builders, build tooling, and CDN. The stack includes Tailwind CSS, Vite, and Cloudflare.
Notably, it's running the same core stack as 3,205 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.
