For most Mac users it's NullDisk: native SwiftUI, a radial sunburst map, a staged removal collector, and zero data collection. DiskPoint users who want treemap views and free pricing will feel at home within minutes.
Yes — GrandPerspective and Disk Inventory X are free and open source with genuine treemap analysis. They lack NullDisk's collector workflow and sunburst map, but they find the biggest hogs fast.
Note the largest folders DiskPoint flagged, then run the same scan in NullDisk and rebuild the cleanup in its removal collector. The full walkthrough is on our switching guide.
DiskPoint is a fine free tool for treemap fans on macOS + Windows + Linux. But if you want the whole job — see, stage, and safely remove — done natively on a modern Mac, NullDisk is the upgrade. 移行ガイド →
