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

SignifyPDF has the basics covered well, with complete legal pages and clean crawl signals. Worth fixing first: missing several security headers 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 the day of launch. Our crawler found 6 technologies on this site, covering build tooling, DNS providers, business email, and os. The stack includes Vite, Google Search Console, and Namecheap DNS.

Notably, it's running the same core stack as 710 other launches.
