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 16 June 2026; the live site may have changed since.
PDF Tools scores well across the board, with a thorough launch checklist and clean crawl signals. Visible gaps: no Strict-Transport-Security, incomplete legal pages, and tracking cookies set before any opt-in.
Launched on Product Hunt on June 16, 2026. The site is hosted on Cloudflare in the United States, with a domain registered 9 weeks before launch. Our crawler found 7 technologies on this site, covering advertising, analytics, build tooling, and CDN. The stack includes Vite, Cloudflare, and Google Ads.
Notably, it's on one of the most common stacks we track, shared by 774 launches and more locked down than the typical Product Hunt launch.

This score is based on structural patterns and is not definitive. Many legitimate sites may trigger signals, and AI-built sites may go undetected. It should be treated as an indicator, not a verdict.
