What is DaisyDisk?

DaisyDisk is a disk space analyzer for macOS that scans internal and external drives, SSDs, HDDs, USB and Thunderbolt devices, network volumes, and cloud storage folders such as Dropbox, Google Drive, OneDrive, and Box to show exactly what is consuming disk space. Results are rendered as an interactive circular sunburst chart, letting users click into folders and drag files to a collection area for deletion, with system and application files automatically protected from accidental removal. The app is built for speed, with the developer claiming a full drive scan takes about 15 seconds versus several minutes in Finder, and it can run with administrator privileges to reveal hidden system files. DaisyDisk is sold as a one-time $9.99 lifetime license covering up to 5 personal Macs, available directly from daisydiskapp.com and on the Mac App Store, with no subscription fees and a 30-day money-back guarantee.

GrandPerspective

AI-suggested

GrandPerspective is a free macOS utility that scans a folder or volume and displays disk usage as a treemap, where each file is drawn as a rectangle sized proportionally to how much space it consumes. This makes it fast to spot the largest files and folders visually rather than digging through nested Finder windows. Released under the GNU General Public License, GrandPerspective supports multiple color-mapping schemes (by file type, size, or modification date), filtering and search, and can compare or combine multiple scans. It is distributed for free from SourceForge, with an optional paid copy on the Mac App Store for users who prefer automatic updates and app-review verification.
