Network diagnostics, reimagined
NetUtil brings back the power of macOS Network Utility with a modern, privacy-focused design. Seven essential tools, one beautiful app.
Why NetUtil?
Apple deprecated Network Utility in macOS Big Sur, leaving users without a native way to run essential network diagnostics. Terminal commands work, but they lack the intuitive interface that made Network Utility so useful.
NetUtil fills that gap with a modern SwiftUI app that wraps the same powerful system tools in an accessible, easy-to-use interface.
Seven Essential Tools
Everything you need to diagnose network issues, all in one place.
Ping
Test connectivity to any host. See response times and packet loss in real-time.
Traceroute
Map the path packets take to reach their destination. Identify bottlenecks and routing issues.
DNS Lookup
Query DNS records for any domain. Resolve hostnames to IP addresses and vice versa.
Netstat
View active network connections and listening ports. Monitor your Mac's network activity.
Whois
Look up domain registration information. Find out who owns a domain and when it expires.
Finger
Query user information from remote systems. A classic protocol still useful for some servers.
Port Scan
Scan hosts for open ports. Discover which services are running on a target system.
Built for macOS
Privacy First
No analytics, no tracking. Your network data stays on your Mac.
Native Performance
Built with SwiftUI for Apple Silicon and Intel Macs. Fast and energy efficient.
Modern Interface
Clean, accessible design that fits right in with macOS Ventura and later.
