The Problem

Checking DNS records requires command-line tools like dig/nslookup that most people can't use. Online tools are ad-heavy and slow. No tool provides an API for automated DNS checks. Developers need quick DNS lookups during debugging. DNS propagation verification requires checking multiple nameservers.
