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 17 July 2026; the live site may have changed since.
PDFSimpl ships with the basics, with a thorough launch checklist, fast page loads, and clean crawl signals. What needs work: missing several security headers, incomplete legal pages, and incomplete email security.
Launched on Product Hunt on July 17, 2026. The site is served through Cloudflare, with a domain registered 7 months before launch. We've detected 9 technologies on this site, covering CDN, analytics, baas, and CSS frameworks. The stack includes Tailwind CSS, Cloudflare, and Cloudflare DNS.
It's running the same core stack as 5,928 other launches.
