TrafficMonitor

TrafficMonitor is a computer utility that allows you to view in real-time your network speed as well as memory and computer usage. Developed by zhongyang219, it is a lightweight solution that supports functions of display in the taskbar, change skin, and historical traffic statistics. This is a completely free and open-source project that you can download on any compatible Windows desktop. On top of that, it is an unobtrusive tool that can keep track of your PC's overall resources. TrafficMonitor is a great alternative to paid monitoring services such as NetWorx, Datadog, and DU Meter.
