This application is a desktop network traffic analyzer that provides real-time monitoring and forensic inspection of data packets. By interfacing directly with low-level system drivers, it captures raw network traffic from physical or virtual adapters to identify communication patterns, track bandwidth usage, and diagnose connectivity issues. The system distinguishes itself through an immediate-mode graphical interface that rebuilds the display state every frame, ensuring high responsiveness during live data updates. It maintains performance by using asynchronous message passing to decouple t

ntopng is a web-based network traffic monitoring tool and flow data aggregator. It functions as a network security monitor, an SNMP network management system, and an industrial protocol analyzer for OT and SCADA environments. The system provides specialized inspection for industrial protocols such as Modbus, DNP3, and IEC 60870. It distinguishes itself through behavioral threat detection, encrypted traffic analysis via handshake fingerprinting, and the ability to identify hardware and operating systems using DHCP and MAC address patterns. Its broader capabilities include real-time traffic an

PCAPdroid is an Android network traffic analyzer and packet capture tool that operates without requiring root access. It functions as a VPN-based firewall and network controller, capable of recording traffic in PCAPng format and blocking connections to specific domains or malicious hosts. The project distinguishes itself through a proxy-based system for decrypting TLS traffic and routing device network traffic through SOCKS5 proxies or the Tor network. It further allows for the modification of live HTTP requests and responses via custom scripts. Its capabilities cover application connection

Portmaster is a host-based network firewall and privacy tool that monitors and controls all system network traffic. It operates by intercepting data packets at the operating system level, allowing it to observe and manage every connection made by local software in real time. The software distinguishes itself through process-aware connection mapping, which correlates active network sockets with specific local applications to provide visibility into data transfers. It utilizes a user-space policy engine to enforce granular security rules, enabling users to restrict internet access, block specif
