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 10 April 2026; the live site may have changed since.

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

Launched on Product Hunt on April 10, 2026. The site is hosted on Vercel, with a domain registered 2 days before launch. Our crawler found 9 technologies on this site, covering analytics, CSS frameworks, developer tools, and DNS providers. The stack includes Tailwind CSS, Google Analytics, and Google Fonts.

It's also running the same core stack as 2,462 other launches.
