Open Source Python Packet Sniffers

Xplico is a Network Forensic Analysis Tool (NFAT). The goal of Xplico is extract from an internet traffic capture the applications data contained. For example, from a pcap file Xplico extracts each email (POP, IMAP, and SMTP protocols), all HTTP contents, each VoIP call (SIP, MGCP, MEGACO, RTP), IRC, WhatsApp... Xplico is able to classify more than 140 (application) protocols. Xplico cam be used as sniffer-decoder if used in "live mode" or in conjunction with netsniff-ng. Xplico is used also in CapAnalysis: http://www.capanalysis.net

justniffer is a TCP sniffer. It reassembles and reorders packets and displays the tcp flow in a customizable way. It can log network traffic in web server log format. It can also log network services performances (e.g. web server response times) and extract http content (images, html, scripts, etc)

DeepDive Sentinel (DDS) is a Windows diagnostic application focused on real-world network performance — not just raw speed. It helps you identify issues that affect gaming, streaming, calls, and remote work by highlighting latency spikes, jitter, and packet loss in a clear monitoring + diagnostics workflow. This is an early-access BETA. Development will continue and features may change. Diagnostics are intended to run locally, and DDS is designed to provide actionable “next step” recommendations based on results.

A Network Packet Sniffer developed in Python 3. Packets are disassembled as they arrive at a given network interface controller and their information is displayed on the screen. This application depends exclusively on the NETProtocols library (also developed and maintained by EONRaider) from version 2.0.0 and above and can be run by any Python 3.8+ interpreter.
