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.

Fylix-Universal File Viewer looks production-ready overall, with complete legal pages, a thorough launch checklist, and clean crawl signals. Main gaps: missing several security headers, tracking cookies set before any opt-in, and no email security records.

Launched on Product Hunt on June 30, 2026. The site is hosted on Vercel. We've detected 12 technologies on this site, covering javascript library, analytics, CSS frameworks, and developer tools. The stack includes Capacitor, Tailwind CSS, and Google Analytics.

It's one of just 6 launches we've crawled on this exact stack.

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.
