Professional network diagnostics for Mac. 10 tools, visual traceroute, device discovery, real-time health scoring — no ads, no cloud. NetMonitor is a professional network monitoring and diagnostics toolkit built for macOS. No accounts. No cloud. No ads. No subscriptions. Just powerful network tools that run locally and respect your privacy. Network Dashboard See your entire network at a glance. A live health score grades your connection quality in real time, combining latency, packet loss, and DNS responsiveness into a single number. Monitor gateway reachability, public IP, ISP details, and live connection events — all in one view. Device Discovery Scan your local network and see every connected device in seconds. NetMonitor uses a multi-phase scanning engine — ARP, Bonjour, TCP probes, and reverse DNS — to find devices other apps miss. View IP and MAC addresses, vendor identification, open ports, running services, and connection history for each device. 10 Built-In Diagnostic Tools • Ping — ICMP with TCP fallback, live latency graphs, and packet statistics • Traceroute — Hop-by-hop path analysis with timing • GeoTrace — Visual traceroute plotted on a world map • World Ping — Test reachability from 20+ global nodes simultaneously • Port Scanner — TCP scanning with preset and custom port ranges • DNS Lookup — Query A, AAAA, MX, NS, TXT, and CNAME records • Speed Test — Download and upload throughput with peak speed and jitter tracking • Network Intel — Live connection stats, DNS resolver health, and smart event feed • WHOIS — Domain registration and ownership lookup • Bonjour Browser — Discover mDNS services on your network GeoTrace See the physical path your traffic takes. GeoTrace plots each hop on a satellite map so you can visualize routing across cities, countries, and continents. iOS Companion Connect to NetMonitor on your iPhone over your local network via Bonjour. Synchronize devices, run remote diagnostics, and monitor your network from either platform. No cloud relay — communication stays on your LAN. Timeline & Event History Every scan, device change, and network event is logged. Scroll back through your network history to spot patterns, track when devices appeared or disappeared, and review past diagnostics. No data ever leaves your device. No analytics. No tracking. Just tools that work.
