CommView
CommView is a powerful network monitor and analyzer designed for LAN administrators, security professionals, network programmers, home users…virtually anyone who wants a full picture of the traffic flowing through a PC or LAN segment. Loaded with many user-friendly features, CommView combines performance and flexibility with an ease of use unmatched in the industry. This application captures every packet on the wire to display important information such as a list of packets and network connections, vital statistics, protocol distribution charts, and so on. You can examine, save, filter, import and export captured packets, view protocol decodes down to the lowest layer with full analysis of over 100 supported protocols. With this information, CommView can help you pinpoint network problems and troubleshoot software and hardware. The newest CommView version 7.0 introduced SSL/TLS traffic decryption on the fly.

VisualEther
VisualEther turns Wireshark packet captures (PCAP/PCAPNG) into readable sequence diagrams — and lets AI coding agents like Claude Code explain, in plain English, why a network session failed.
Wireshark shows every packet but not the conversation. VisualEther draws it directly from the capture — frame-accurate and reproducible — using 82+ built-in protocol templates spanning 5G NR, 5G core, LTE, IMS/VoLTE, SIP/RTP, BGP, OSPF, DNS, HTTP/2, HTTP/3, TLS, Kerberos, Diameter, GTP, and industrial protocols (Modbus, DNP3, EtherNet/IP).
A built-in MCP server extracts only the messages and fields that matter, so an AI agent reads kilobytes of structured data instead of megabytes of raw packets — then runs an author-debug-verify loop, citing frame numbers as evidence. Built on tshark: anything Wireshark can dissect, VisualEther can diagram.
