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 30 June 2026; the live site may have changed since.
Calendi is partway there, with a thorough launch checklist, well-configured email security, and clean crawl signals. What needs work: missing several security headers, incomplete legal pages, and tracking cookies set before any opt-in.
Launched on Product Hunt on June 30, 2026. The site is served through Cloudflare, with a domain registered 8 weeks before launch. The crawl picked up 11 technologies on this site, covering advertising, analytics, CDN, and DNS providers. The stack includes Next.js, React, and Cloudflare.
For context, it's running the same core stack as 600 other launches.

Vibe Score Breakdown How?

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.
