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 9 June 2026; the live site may have changed since.
Qpher scores well across the board, with complete legal pages, a complete set of security headers, and a thorough launch checklist. Main gaps: incomplete email security.
Launched on Product Hunt on June 9, 2026. The site is hosted on Amazon.com in the United States, with a domain registered 5 months before launch. We've detected 9 technologies on this site, covering hosting, CSS frameworks, DNS providers, and transactional email. The stack includes Next.js, React, and Tailwind CSS.
It's one of 28 launches on this exact stack and more locked down than the typical Product Hunt launch.

Readiness Breakdown How?

Indicative grade from a single automated render, not a substitute for Lighthouse or field data, and not part of the StackScope score.
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.
