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 18 April 2026; the live site may have changed since.
Line Cal is largely in shape, with complete legal pages, fast page loads, and clean crawl signals. What needs work: missing several security headers and incomplete email security.
Launched on Product Hunt on April 18, 2026. The site is served through Cloudflare, with a domain registered 10 months before launch. The crawl picked up 9 technologies on this site, covering CDN, CSS frameworks, developer tools, and DNS providers. The stack includes Tailwind CSS, Vue.js, and Brevo.
For context, it's running the same core stack as 242 other launches.

Readiness Breakdown How?
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.
