AppTerrain

A network bandwidth monitor for the Mac

You have network questions

Sure, the speed tests may say 20 Mbps, but is it steady and strong or jumpy and unstable? Is that file still uploading or has it stalled? Is some other process taking up most of your bandwidth? What’s randomly uploading – could it be that free coin wallet you downloaded?

Find out with AppTerrain.

Tons of details

See details for every process with a network connection. Track how much data each process has uploaded and downloaded.

See the connections for each process, both active and past, the amount uploaded and downloaded, time last active, ports used and more.

Want a smaller view? There's a mini-window that shows overall system usage.

See past processes (shown in grey). Their connection details will show the most recent activity.

Get info on common processes. This list will continue to grow!

If the process's path is available, it can be viewed with the info button and opened in Finder with the arrow button.

Perfect macOS citizen

Universal binary

Lovingly built to run natively, on both Intel and Apple Silicon.

No setup

There’s nothing to configure or install (or uninstall) – AppTerrain uses only the tools and libraries already on your Mac.

Great performance

AppTerrain uses very little CPU and memory. When the windows are closed or hidden, the app uses minimal CPU to collect the data.

No cruft

When the app is closed, nothing remains running.

Worried about privacy?

Us too. Nothing gets logged – the data’s only in memory, so when you clear the history or quit the app, POOF! The history is gone.

The app can’t see the actual network data, only how much was sent and where.

If you do want to log the raw data, though, you have that option, too.
