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 20 June 2026; the live site may have changed since.
Sleeve is partway there, with complete legal pages and a thorough launch checklist. Worth fixing first: missing several security headers, no robots.txt or sitemap, and incomplete email security.
Launched on Product Hunt on June 20, 2026. The site is hosted on Amazon.com in the United States, with a domain registered in 2014. The crawl picked up 5 technologies on this site, covering CSS frameworks, frameworks, hosting, and meta-frameworks. The stack includes Next.js, React, and Tailwind CSS.
For context, it's running the same core stack as 8,008 other launches.

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

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.
