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 7 August 2026; the live site may have changed since.

1PDF.best ships with the launch fundamentals in place, with complete legal pages, a thorough launch checklist, and clean crawl signals. Worth fixing first: no Content-Security-Policy and incomplete email security.

Launched on Product Hunt on August 7, 2026. The site is hosted on Vercel, with a domain registered 3 weeks before launch. Our crawler found 16 technologies on this site, covering advertising, analytics, consent tooling, and CSS frameworks. The stack includes Google, Google Funding Choices, and Next.js.

It's also running the same core stack as 12,599 other launches and tighter on security headers than most Product Hunt launches.
