Overview

NetSniffer watches your local network activity so you don't have to guess. It tracks bandwidth over time and attributes traffic to the processes responsible, helping you spot the app that's saturating your connection or quietly talking to the internet. Inspection happens locally and the footprint is deliberately tiny, so you can leave it running in the background without paying for it in resources.
