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 19 June 2026; the live site may have changed since.
DiagramPreview looks production-ready overall, with complete legal pages, a thorough launch checklist, and clean crawl signals. Worth fixing first: missing several security headers, tracking cookies set before any opt-in, and incomplete email security.
Launched on Product Hunt on June 19, 2026. The site is hosted on Amazon.com in the United States, with a domain registered 1 week before launch. We've detected 14 technologies on this site, covering seo, analytics, CSS frameworks, and DNS providers. The stack includes Next.js, React, and Tailwind CSS.
It's running the same core stack as 7,957 other launches.

Indicative grade from a single automated render, not a substitute for Lighthouse or field data, and not part of the StackScope score.
Vibe Score Breakdown How?
| Signal | Points |
|---|---|

| AI stack signals | +10 |
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.
