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

Uno is early-stage. Worth fixing first: missing several security headers, incomplete legal pages, and no sitemap.

Launched on Hacker News on June 3, 2026. The site is hosted on Cloudflare in the United States, with a domain registered in 1999. We've detected 4 technologies on this site, covering CDN, DNS providers, hosting, and protocol. The stack includes Cloudflare, Cloudflare DNS, and HTTP/3.

It's running the same core stack as 174 other launches.

SignalPoints
AI writing signals +3

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.
