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 4 May 2026; the live site may have changed since.

PrivatePDF covers some of the launch checklist, with a thorough launch checklist, fast page loads, and clean crawl signals. Main gaps: missing several security headers, incomplete legal pages, and no email security records.

Launched on Product Hunt on May 4, 2026. The site is hosted on HETZNER-AS in Germany. Our crawler found 4 technologies on this site, covering DNS providers, package cdn, seo, and servers. The stack includes cdnjs, Google Search Console, and nginx.

✓ Twitter card meta tags

✓ Canonical URL declared

✓ Responsive viewport meta tag
