bandwhich – Terminal Bandwidth Utilization Tool

bandwhich is a modern terminal bandwidth utilization tool written in Rust that displays current network utilization by process, connection, and remote IP/hostname. It provides a clear, colorful interface showing which processes are using bandwidth and where they’re connecting.

Unlike traditional tools that show only aggregate bandwidth, bandwhich breaks down usage by application and destination, helping you quickly identify what’s consuming your network resources. Its modern design and informative display make network monitoring more intuitive.
