Description

10 professional network tools. Zero cloud. Zero ads. Zero subscriptions. Everything runs locally on your Mac.

NetMonitor is a complete network monitoring and diagnostics toolkit built for macOS. Scan your network, discover every connected device, trace routes across the globe, and diagnose issues in seconds — all without creating an account or sending a single byte off your machine.

WHO IT'S FOR

Network admins — Monitor infrastructure and catch rogue devices

Developers — Debug connectivity, inspect DNS, scan ports

Homelab enthusiasts — Map your entire network and track every device

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

Find devices other apps miss. NetMonitor's multi-phase scanning engine uses ARP, Bonjour, TCP probes, and reverse DNS to build a complete picture of your network. See IP and MAC addresses, vendor names, open ports, running services, and connection history for every 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

WiFi Heatmap — Walk-around signal survey with floorplan overlay

WHOIS — Domain registration and ownership lookup

Bonjour Browser — Discover mDNS services on your network

WIFI HEATMAPPING

Import a floorplan or use freeform mode, then walk around to map signal strength across your space. Identify dead zones and optimize access point placement with real data instead of guesswork.

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.

IPHONE 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.
