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 26 April 2026; the live site may have changed since.
Secure PDF Browser is missing several launch fundamentals. What needs work: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.
Launched on Product Hunt on April 26, 2026. The site is served through Cloudflare. Our crawler found 8 technologies on this site, covering analytics, CDN, CSS frameworks, and DNS providers. The stack includes Tailwind CSS, Cloudflare, and Cloudflare DNS.
It's also running the same core stack as 5,950 other launches.
