Own this Launch?

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

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

Launched on Product Hunt on July 12, 2026. The site is hosted on Contabo GmbH in Germany, with a domain registered 2 days before launch. The crawl picked up 11 technologies on this site, covering APIs, CSS frameworks, developer tools, and DNS providers. The stack includes Tailwind CSS, Cloudflare DNS, and Google Fonts.

For context, it's running the same core stack as 5,693 other launches and tighter on security headers than most Product Hunt launches.
