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 25 April 2026; the live site may have changed since.

PDF Pro — Private PDF Tools ships with the launch fundamentals in place, with complete legal pages, a complete set of security headers, and a thorough launch checklist. Worth fixing first: incomplete email security.

Launched on Product Hunt on April 25, 2026. The site is hosted on Vercel, with a domain registered 1 week before launch. The crawl picked up 13 technologies on this site, covering auth, baas, collaboration, and CSS frameworks. The stack includes Google OAuth, Google Sign-In, and Svelte.

For context, it's on a stack we've seen on only 3 launches and tighter on security headers than most Product Hunt launches.
