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 17 June 2026; the live site may have changed since.
The Ruby AI Newsletter is largely in shape, with complete legal pages, a thorough launch checklist, and well-configured email security. What needs work: missing several security headers.
Launched on Hacker News on June 16, 2026. The site is hosted on Cloudflare in the United States, with a domain registered in 2020. The crawl picked up 14 technologies on this site, covering social embeds, security, advertising, and build tooling. The stack includes Tailwind CSS, Vite, and Beehiiv.
For context, it's running the same core stack as 3,205 other launches.

Vibe Score Breakdown How?
| Signal | Points |
|---|---|

| AI layout signals | +5 |
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.
