DuckDisk

DuckDisk is a powerful open-source storage analysis tool designed specifically for macOS users seeking clear and actionable insights into their disk usage. Unlike traditional visual maps, DuckDisk offers a table-first, WizTree-style interface that displays detailed information such as size, allocated space, parent percentages, item counts, and file-type totals. It supports scanning local disks, cloud storage services like OneDrive and Google Drive, and remote servers via SSH—all within a single, user-friendly app. Notably, cloud scans use only metadata, ensuring privacy by not downloading actual file contents. As an Apple-notarized application available on the Mac App Store, DuckDisk combines transparency, privacy, and ease of use, making it ideal for developers, IT professionals, and anyone looking for precise storage insights without the clutter of colorful maps.
