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

XO has the basics covered well, with a complete set of security headers, a thorough launch checklist, and fast page loads. Main gaps: incomplete legal pages and incomplete email security.

Launched on Hacker News on August 12, 2026. The site is served through Cloudflare, with a domain registered 11 months before launch. Our crawler found 13 technologies on this site, covering javascript library, analytics, CDN, and CSS frameworks. The stack includes Tailwind CSS, Cloudflare, and Cloudflare DNS.

It's also on one of the most common stacks we track, shared by 6,918 launches and more locked down than the typical Hacker News launch.

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.
