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

PDFTools scores well across the board, with complete legal pages, a thorough launch checklist, and clean crawl signals. Visible gaps: no Permissions-Policy, tracking cookies set before any opt-in, and no email security records.

Launched on Product Hunt on June 28, 2026. The site is hosted on Amazon.com in the United States. Our crawler found 16 technologies on this site, covering advertising, analytics, hosting, and ai api. The stack includes Next.js, React, and Tailwind CSS.

Notably, it's one of 40 launches on this exact stack and more locked down than the typical Product Hunt launch.
