TrafficMonitor is a Windows desktop application that displays a small floating window showing your computer's current network speed, CPU usage, and memory usage in real time. Think of it as a lightweight system monitor that stays visible on your screen at all times without opening Task Manager. The app shows two main metrics continuously: upload and download network speeds for your current connection, and the percentage of CPU and RAM being used. If your computer has multiple network adapters, for example, both Wi-Fi and ethernet, you can choose which connection to monitor. You can also click through to see more detailed network information. One of its most useful features is the ability to embed this information directly into the Windows taskbar as a persistent widget alongside your other taskbar elements, so you can always glance at your system stats without any floating window taking up screen space. The display is fully customizable: you can choose which metrics to show, change the font and colors, and apply downloadable visual themes called "skins." The skin system is simple enough that users can create their own using image files and a configuration file. The application also tracks cumulative network usage over time, so you can see historical traffic statistics rather than just the current speed. Someone would use TrafficMonitor when they want quick at-a-glance visibility into how their PC is performing, particularly useful for gamers checking for lag, people on metered internet connections tracking data usage, or anyone who simply wants to know what their computer is doing at a glance without running a full system monitoring tool. The tech stack is C++ for Windows, using the Win32 API and MFC (Microsoft Foundation Classes). Hardware monitoring functionality uses the open-source LibreHardwareMonitor library internally.
