Own this Launch?

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.

KeyPDF looks production-ready overall, 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 8, 2026. The site is served through Cloudflare, with a domain registered 3 months before launch. We've detected 7 technologies on this site, covering analytics, CDN, DNS providers, and email forwarding. The stack includes Cloudflare, Cloudflare DNS, and Cloudflare Email Routing.
