Sniffnet Overview
Sniffnet is a free, open-source network-monitoring application for Windows, macOS, and Linux that lets you watch your computer's internet traffic in a clear, friendly interface. Rather than the dense output of professional analyzers, it presents real-time charts and statistics of incoming and outgoing connections, showing which hosts and countries your machine is talking to, how much data each uses, and which protocols are involved, with filtering and notifications. It is aimed at curious users and learners who want visibility into their network activity without a steep learning curve. Because the download is a complete installer, Sniffnet installs without needing a connection during setup. It supports exporting reports, works across common network adapters, and is actively developed with a growing feature set. You can reach the official Sniffnet download from Giuliano Bellini via the link on this page.
