Description
The disk is nearly full and you have no idea which folder is eating it; clicking through Finder and adding up sizes by hand gets old fast. WinDirStat solved this on Windows, and MacDirStat does the same on the Mac: it scans the whole disk and draws every file as a colored rectangle.
A rectangle's area is the space it uses and its color is the file type, with files grouped inside their folders, so the biggest offenders jump out at a glance. An inspector panel lists total size, file count and a breakdown by type, and you can reveal or copy the path of anything you select. It is a native SwiftUI app for Apple silicon and Intel, signed and notarized by Apple, fully offline with no ads, accounts or tracking.
Interactive treemap: Scan the whole disk and see usage as nested colored rectangles; click one to drill into what it contains.
Color by file type: Documents, video, archives, code and caches each get a color, with a category breakdown beside the map.
Inspector panel: Shows size, allocated space, file and directory counts and modified date, with one-click Reveal in Finder and Copy Path.
Fully offline: No network, no account, no subscription or ads, and MIT-licensed.
Native and notarized: Written in SwiftUI for Apple silicon and Intel, requires macOS 15 or later; grant Full Disk Access to scan protected folders.
