PacketSnitch vs Xplico

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.

Xplico is free, open-source network forensic software that extracts application data from PCAP traffic captures. It can recover email, HTTP content, VoIP calls, and FTP or TFTP data, with protocol support for HTTP, SIP, IMAP, POP, SMTP, TCP, UDP, and IPv6. Port Independent Protocol Identification recognizes application protocols without depending on port numbers. Processing supports multithreading and realtime operation, although speed depends on flows, protocol types, and computer resources. Results can be written to files or SQLite and MySQL databases. A web interface lets concurrent users manage one or more cases, using SQLite, MySQL, or PostgreSQL as a backend. Modular capture, dissector, and dispatcher components can target files, databases, or network sockets. Downloads cover Fedora, CentOS/RHEL, and Ubuntu, alongside source code and a VirtualBox image. The free plan costs nothing; data-entry and input-file counts are unrestricted, with hard-drive size as the stated limit.
