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 23 June 2026; the live site may have changed since.

Xu has the basics covered well, with complete legal pages, fast page loads, and clean crawl signals. Visible gaps: missing several security headers and incomplete email security.

Launched on Product Hunt on June 23, 2026. The site is hosted on Cloudflare in the United States, with a domain registered in 2025. Our crawler found 5 technologies on this site, covering analytics, CDN, CSS frameworks, and meta-frameworks. The stack includes Astro, Tailwind CSS, and Cloudflare.

Notably, it's on one of the most common stacks we track, shared by 303 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.
