A smart, Flask-based network monitoring tool that scans your local network, identifies connected devices, and helps detect unknown or potentially unwanted connections.
Network Visualiser provides clear visibility into your local network. It performs fast scans to discover active devices, retrieves key details like IP address, MAC address, and hostname, and helps identify unfamiliar or suspicious devices connected to your network.
Whether you're debugging your network, monitoring usage, or checking for unauthorized access, this tool provides a simple and effective interface.
