NetUtil

A native macOS application that restores network diagnostic utilities removed from the operating system, providing ping, traceroute, DNS lookup, port scan, netstat, and whois without requiring terminal commands or syntax memorization. It is for software developers, IT professionals, and general Mac users who need to diagnose connectivity, DNS, and port issues on Mac. It is positioned as a free replacement for the former Apple Network Utility, rebuilt with a modern SwiftUI interface that runs locally on Apple Silicon and Intel Macs.
