5 Best Free Open Source Bandwidth Monitor Software For Windows

Here is a list of best free open source bandwidth monitor software for Windows. Through these open source software, you can easily find out the bandwidth of your network, just like any standard bandwidth monitoring software. However, these software come with open source license which allows you to download, study, and modify their source codes.

Using these software, you can easily find out the current bandwidth of your network. To determine network bandwidth, these software show you real-time upload and download speeds of your network. These software also display graphs showing the fluctuations in upload and download speeds over a period of time. The upload and download speed graphs are shown in different colors by these software to differentiate them. There are also some software who do not show graphs and only show you the current upload and download speed values. Besides real-time or current speed, you can also find average and peak download/upload speeds of your network. Some of these software also let you adjust graph parameters (colors, speed value, etc.), speed units, refresh interval, etc.

A few of these software also show you various statistics about your network like network interface statistics, global statistics, TCP statistics, TCP connections, etc. Plus, you can also find additional features in some of these software, like Ping Address, History Traffic, Traceroute Utility, and more. In general, all of these software are quite simple and easy to use. Go through the list to know more about these software.
