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 August 2026; the live site may have changed since.
PaperbackKit is partway there, with a thorough launch checklist and clean crawl signals. What needs work: missing several security headers, incomplete legal pages, and incomplete email security.
Launched on Product Hunt on August 18, 2026. The site is hosted on Fly.io, with a domain registered 2 weeks before launch. The crawl picked up 8 technologies on this site, covering CSS frameworks, DNS providers, business email, and frameworks. The stack includes Next.js, React, and Tailwind CSS.
For context, it's one of 58 launches 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.
