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 July 2026; the live site may have changed since.
OnDevicePDF ships with the launch fundamentals in place, with complete legal pages, a complete set of security headers, and a thorough launch checklist. What needs work: tracking cookies set before any opt-in.
Launched on Product Hunt on July 13, 2026. The site is hosted on Vercel, with a domain registered 11 months before launch. We've detected 14 technologies on this site, covering analytics, advertising, ai api, and CSS frameworks. The stack includes Next.js, React, and Tailwind CSS.
It's running the same core stack as 10,131 other launches and tighter on security headers than most Product Hunt launches.
