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 2 July 2026; the live site may have changed since.

Wolf PDF has the basics covered well, with complete legal pages, a thorough launch checklist, and fast page loads. Worth fixing first: missing several security headers, tracking cookies set before any opt-in, and incomplete email security.

Launched on Product Hunt on July 2, 2026. The site is hosted on Railway and served through Cloudflare, with a domain registered 4 months before launch. Our crawler found 12 technologies on this site, covering analytics, CDN, CSS frameworks, and DNS providers. The stack includes Next.js, React, and Tailwind CSS.

It's also running the same core stack as 373 other launches.
