It builds a database of all devices by MAC address, hostname, and vendor, alerting you when new devices appear or unknown devices connect. Features include automatic device recognition, ARP scanning, WiFi connected device tracking, online/offline notifications, device history with timestamps, webhook alerts (Discord, Telegram, etc.), and a beautiful dashboard. Perfect for home network security - know exactly what's connected to your network at all times.
