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 July 2026; the live site may have changed since.

YourPDF Checker looks production-ready overall, with complete legal pages, well-configured email security, and clean crawl signals. Worth fixing first: missing several security headers.

Launched on Product Hunt on July 30, 2026. The site is served through Cloudflare, with a domain registered 12 weeks before launch. We've detected 11 technologies on this site, covering analytics, CDN, CSS frameworks, and developer tools. The stack includes Tailwind CSS, Cloudflare, and Cloudflare DNS.

It's running the same core stack as 6,431 other launches.
