About DuckDisk for Mac
DuckDisk is a free, open-source disk usage analyzer for Mac. Besides scanning local drives, it can also analyze cloud and SSH storage, which makes it useful for developers and anyone who keeps files on remote servers.
Instead of a chart, DuckDisk presents results in a sortable table — a fast, practical view when you simply want to know which folders are biggest and drill down from there.
If you like clear numbers over visualizations, DuckDisk is a lightweight option worth keeping next to your uninstaller.
