What is TCP Viewer?

TCP Viewer is a macOS packet viewer for real-time network packet capture and analysis. It uses AppKit, libpcap, and Wireshark libraries. Users can easily examine TCP traffic on their Mac systems. The software simplifies the packet capture process by allowing users to select an interface, start recording, and maintain packet capture during high network activity. Users can open PCAP and PCAPNG files through drag-and-drop, preview packets immediately, and review saved data in a Mac-centric packet interface.

TCP Viewer filters out unnecessary information for clear inspection. It enables users to open decoded fields, filter noise, save evidence, group traffic, and apply protocol filters. Users can export captures as PCAP or PCAPNG files for sharing or future debugging. The software provides access to Wireshark-grade packet data within a Mac-focused interface.
