NetMon
Lightweight Network Bandwidth Monitor for Windows — inspired by DU Meter.
NetMon is a minimalist, high-performance network monitoring widget designed for Windows. Inspired by the classic DU Meter, it provides real-time insights into your upload and download speeds through a sleek, unobtrusive interface. Built with C# and WinForms on .NET 8, NetMon is optimized for users who need precise data tracking without the resource overhead of traditional monitoring suites.
