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.

Riverbed Packet Analyzer
Riverbed Packet Analyzer accelerates real-time network packet analysis and reporting of large trace files through an intuitive graphical user interface and a broad selection of pre-defined analysis views. It enables users to quickly identify and troubleshoot complex network and application performance issues down to the bit level, with full integration with Wireshark. By simply dragging and dropping preconfigured analysis views onto a group of virtual interfaces or a packet trace file, users can see results immediately, transforming hours of work into seconds. The tool facilitates the capture and merging of multiple trace files, allowing for precise pinpointing of problems across multiple segments. Additionally, it provides the capability to zoom into a 100-microsecond view of the network to identify utilization spikes or microbursts that can saturate a gigabit network and cause significant issues.

Sniffnet
Sniffnet is a network monitoring tool designed to help users easily keep track of their Internet traffic. Whether gathering statistics or inspecting in-depth network activities, Sniffnet provides comprehensive coverage. It emphasizes user experience, ensuring ease of use compared to other cumbersome network analyzers. Completely free and open source, Sniffnet is dual-licensed under MIT or Apache-2.0, with the full source code available on GitHub. Developed entirely in Rust, it leverages this modern programming language to build efficient and reliable software, emphasizing performance and safety. Key features include selecting a network adapter to inspect, applying filters to observed traffic, viewing overall statistics and real-time charts of Internet traffic, exporting comprehensive capture reports as PCAP files, identifying over 6,000 upper-layer services, protocols, trojans, and worms, discovering domain names and ASNs of hosts, pinpointing connections in the local network.
