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

PDF Vaulty ships with the basics, with fast page loads and clean crawl signals. Visible gaps: missing several security headers, incomplete legal pages, and no email security records.

Launched on Product Hunt on April 3, 2026. The site is hosted on DFINITY Internet Computer. We've detected 7 technologies on this site, covering CSS frameworks, developer tools, DNS providers, and transactional email. The stack includes Tailwind CSS, Amazon SES, and Cloudflare DNS.

It's one of only 10 launches we've crawled running DFINITY Internet Computer.
