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

CometPDF has the basics covered well, with a thorough launch checklist and clean crawl signals. Visible gaps: missing several security headers, incomplete legal pages, and incomplete email security.

Launched on Product Hunt on June 9, 2026. The site is hosted on Amazon.com in the United States, with a domain registered 1 week before launch. Our crawler found 5 technologies on this site, covering DNS providers, business email, hosting, and security. The stack includes Google Search Console, HSTS, and Namecheap DNS.

Notably, it's on one of the most common stacks we track, shared by 1,264 launches.
