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 13 April 2026; the live site may have changed since.
FlexCalls looks production-ready overall, with complete legal pages, a thorough launch checklist, and clean crawl signals. Worth fixing first: missing several security headers and no email security records.
Launched on Product Hunt on April 2, 2026. The domain was registered 7 months before launch. We've detected 11 technologies on this site, covering seo, AI builders, CSS frameworks, and developer tools. The stack includes Tailwind CSS, Google Fonts, and Google Search Console.
It's running the same core stack as 5,948 other launches.

Readiness Breakdown How?
Vibe Score Breakdown How?

| AI palette 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.
