Sniffnet is an open-source network monitoring tool aimed at detailed real-time traffic analysis. Developed in Rust, the software combines performance, stability, and security, offering a modern and intuitive interface for visualizing and inspecting data that flows through the network.
It captures packets directly from the network interface and displays complete information about each active connection — including source and destination IPs, ports used, protocol (TCP, UDP, ICMP, etc.), volume of data sent and received, and real-time transfer rate. Additionally, Sniffnet automatically identifies countries and providers associated with IP addresses, allowing you to understand where your network traffic comes from and where it goes.
The tool provides graphical dashboards that present real-time statistics, such as bandwidth usage, number of open connections, and traffic history. It is possible to apply advanced filters to monitor only specific types of protocols, devices, IP addresses, or ports — a feature particularly useful for administrators and security analysts who need to investigate anomalous behaviors.
Another highlight of Sniffnet is its lightweight nature: it consumes few system resources, even during continuous monitoring.
Ideal for network administrators, cybersecurity professionals, and users who want to better understand the behavior of their connection, Sniffnet offers a transparent and powerful way to observe what really happens in your network — from legitimate connections to suspicious activities that may compromise performance or privacy.
