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

PDFOmni ships with the launch fundamentals in place, with complete legal pages, a thorough launch checklist, and fast page loads. Worth fixing first: missing Content-Security-Policy and Strict-Transport-Security and incomplete email security.

Launched on Product Hunt on June 11, 2026. The site is hosted on Cloudflare in the United States, with a domain registered 1 week before launch. The crawl picked up 11 technologies on this site, covering advertising, analytics, build tooling, and CDN. The stack includes Google Funding Choices, Vite, and Cloudflare.

For context, it's running the same core stack as 723 other launches and tighter on security headers than most Product Hunt launches.
