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 8 July 2026; the live site may have changed since.

PDFCraft has the basics covered well, with clean crawl signals. Visible gaps: missing several security headers, incomplete legal pages, and tracking cookies set before any opt-in.

Launched on Product Hunt on July 8, 2026. The site is hosted on Vercel and served through Cloudflare, with a domain registered 10 months before launch. Our crawler found 11 technologies on this site, covering analytics, CDN, CSS frameworks, and developer tools. The stack includes Tailwind CSS, Cloudflare, and Google Analytics.

It's also on one of the most common stacks we track, shared by 2,306 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.
