PacketSnitch vs termshark

PacketSnitch is a desktop application for investigating network traffic in PCAP and PCAPNG captures. It turns files into searchable, protocol-aware information and can extract hosts, credentials, certificates, files, locations, protocols, anomalies and threat-intelligence hits. Analysis tools include stream reconstruction, protocol decoding, complex filters, visualizations, threat-intelligence scoring, file carving, GeoIP enrichment and capture workspaces. Traffic decryption, flow analysis and CLI tools are also listed. ZIP-packaged plugins can be installed through Settings. The bundled Python backend parses captures locally, and the maker says captures are not uploaded. Optional network activity includes configured LLM calls, threat-intelligence lookups and anonymous metrics; metrics can be disabled in Settings. Optional LLM analysis supports Ollama, OpenRouter and Cohere when configured. New installations get full features in Demo mode for 30 days, then move to Free mode with core analysis and reduced functionality. Prebuilt installers are available for Windows 10/11 and Linux DEB or RPM distributions. macOS has no signed installer, though running from source is described. The maker says analysis outputs may not be accurate or complete and should be independently validated before consequential use.

termshark is a terminal interface for tshark, inspired by Wireshark, for inspecting packet captures and network traffic. It can read pcap files or sniff live interfaces when tshark is permitted, including on a remote machine where a capture need not be copied to a desktop. Users can apply Wireshark display filters, group conversations by protocol, and reassemble TCP and UDP streams. Packet search covers packet lists, structures and bytes, using text, regular expressions, hexadecimal input or display filters. The guide also describes importing a Wireshark column set when the configuration can be found, and transferring the current capture with Magic Wormhole. The project lists Linux, macOS, BSD variants, Android through Termux and Windows. It is free and MIT-licensed, and the project says its Go implementation builds as one executable on each platform. Packet analysis requires tshark 1.10.2 or higher in the user's PATH. The project notes that some tshark features are not yet exposed by termshark; the latest listed release is v2.4.0, dated July 11, 2022.
