DuckDisk

What is DuckDisk?

DuckDisk is a free, open-source macOS storage analyzer built for people who want answers, not just colorful maps. Its WizTree-style, table-first tree keeps size, allocated space, parent %, item counts, and file-type totals visible while you drill down. Scan local disks, OneDrive, Google Drive, and SSH in one app. Cloud scans use metadata only—file contents are not downloaded. The release is Apple-notarized and available on the Mac App Store.
