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 22 May 2026; the live site may have changed since.
HeadlessPDF ships with the launch fundamentals in place, with complete legal pages, a complete set of security headers, and a thorough launch checklist.
Launched on Hacker News on May 22, 2026. The site is served through Cloudflare, with a domain registered 4 months before launch. We've detected 14 technologies on this site, covering CSS frameworks, security, AI builders, and captcha. The stack includes Bootstrap, Tailwind CSS, and Bolt.
It's running the same core stack as 139 other launches and tighter on security headers than most Hacker News launches.
