SniffnetUnderrated
A friendly network monitor that shows what your machine is talking to, in real time.

Best for
People who want to see bandwidth use and spot unexpected connections without a packet-analysis degree.
Why it deserves attention
Sniffnet groups traffic by application, host, and country, charts throughput, and lets you filter by protocol or address while it runs. It also flags suspicious hosts and can export reports, all through a native GUI rather than a terminal. It is Apache-2.0 with 41,000 GitHub stars and builds for Windows, macOS, and Linux. It is a monitor, not a firewall: it shows connections but does not block them.
