Free for macOS 15+
Know who's on your network — always.
Netfox is a native macOS network monitor. Every connected device, when it joined, and what's new — at a glance. No cloud, no account, no telemetry.
The Problem
Router admin pages
Show MACs and IPs, but dated UI and no history. You only see what’s online right now.
Terminal tools
Give precise data, but no big picture. One scan at a time, results never persist.
Vendor cloud apps
Beautiful, but send your data to the cloud and lock you into one router brand.
The Solution
Features
Multi-Source Discovery
Bonjour, ARP and active probing run together. Apple devices, dumb IoT, quiet hosts — all in the same list.
Per-Device History
First seen, last seen, every online/offline transition. Timeline survives across launches.
New-Device Alerts
In-app inbox plus native macOS notifications. Persistent log of everything that ever fired.
Native macOS
Built in SwiftUI for macOS 15+. Follows system appearance. Universal binary.
No Account, No Cloud
Data stays on your Mac. No telemetry, no sign-up, no vendor lock-in.
Signed & Notarized
Developer ID + Apple notarization. Gatekeeper accepts it on first open, no security workarounds.
