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 17 June 2026; the live site may have changed since.

Underlayer ships with the launch fundamentals in place, with complete legal pages, a thorough launch checklist, and clean crawl signals. What needs work: missing Permissions-Policy and Content-Security-Policy and no email security records.

Launched on Product Hunt on June 17, 2026. The site is hosted on Hetzner Online GmbH in Germany, with a domain registered 7 weeks before launch. Our crawler found 9 technologies on this site, covering CSS frameworks, DNS providers, transactional email, and frameworks. The stack includes Next.js, React, and Tailwind CSS.

Notably, it's running the same core stack as 2,692 other launches and tighter on security headers than most Product Hunt launches.
