Netfox

Netfox is a native macOS network monitoring tool designed for users who want a comprehensive view of all devices connected to their local network. By leveraging protocols such as Bonjour, ARP, SSDP, and NetBIOS, along with active probing, it displays every connected device—ranging from Apple gadgets and smart TVs to IoT devices and printers—in a single, live window. Its detailed device history tracks first and last appearances, as well as online/offline transitions, providing valuable insights for security and management. With five alert types, users can be notified about new, risky, or returning devices, enhancing network security. The built-in security scan checks common ports with plain-English reports, simplifying vulnerability assessment. Built entirely in SwiftUI, Netfox emphasizes privacy: it runs locally without cloud storage, accounts, or telemetry, ensuring user data stays on the device. As a free tool, it offers a user-friendly, privacy-focused solution for network monitoring on macOS.
