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 23 June 2026; the live site may have changed since.

Peppolpdf has the basics covered well, with complete legal pages, a thorough launch checklist, and clean crawl signals. What needs work: missing several security headers, tracking cookies set before any opt-in, and incomplete email security.

Launched on Product Hunt on June 23, 2026. The site is hosted on Amazon.com in the United States. Our crawler found 12 technologies on this site, covering analytics, CSS frameworks, DNS providers, and business email. The stack includes Next.js, React, and Tailwind CSS.

Notably, it's running the same core stack as 8,316 other launches.
