Watchman - A lightweight, Open Source Network Monitor for Windows & Mac

Watchman shows which apps are using your internet, even when they run quietly in the background. It also tracks live download and upload speed, CPU and RAM usage, traffic history, connection health, M-Lab speed tests, CSV export, and a compact taskbar widget. Local-first, no account required.
