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 11 June 2026; the live site may have changed since.
Duplex looks production-ready overall, with a thorough launch checklist and clean crawl signals. Main gaps: missing several security headers, incomplete legal pages, and no email security records.
Launched on Product Hunt on June 11, 2026. The site is hosted on Amazon.com in the United States. We've detected 5 technologies on this site, covering build tooling, CSS frameworks, hosting, and security. The stack includes Tailwind CSS, Vite, and Google Search Console.
It's on one of the most common stacks we track, shared by 1,481 launches.

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.
