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 April 2026; the live site may have changed since.
PDF Tools by Renderlog is largely in shape, with complete legal pages, a thorough launch checklist, and clean crawl signals. Worth fixing first: missing several security headers and incomplete email security.
Launched on Product Hunt on April 28, 2026. The site is hosted on Vercel, with a domain registered 3 weeks before launch. The crawl picked up 5 technologies on this site, covering frameworks, hosting, meta-frameworks, and security. The stack includes Next.js, React, and Google Search Console.
For context, it's running the same core stack as 2,292 other 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.
