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 10 April 2026; the live site may have changed since.
SemPDF 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, tracking cookies set before any opt-in, and no email security records.
Launched on Product Hunt on April 7, 2026. The site is hosted on Vercel, with a domain registered 4 weeks before launch. Our crawler found 12 technologies on this site, covering transactional email, analytics, auth, and CSS frameworks. The stack includes Auth.js, Next.js, and React.
It's also running the same core stack as 10,671 other launches and tighter on security headers than most Product Hunt launches.

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.
