What is the best alternative to DaisyDisk for Mac?
For most Mac users it's NullDisk: native SwiftUI, a radial sunburst map, a staged removal collector, and zero data collection. DaisyDisk users who want sunburst views and paid pricing will feel at home within minutes.
Is there a free alternative to DaisyDisk?
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.
How do I switch from DaisyDisk to NullDisk?
Note the largest folders DaisyDisk flagged, then run the same scan in NullDisk and rebuild the cleanup in its removal collector. The full walkthrough is on our switching guide.
Sa madaling salita
DaisyDisk is a capable tool for sunburst fans on macOS. But if you want the whole job — see, stage, and safely remove — done natively on a modern Mac, NullDisk is the upgrade. Gabay sa paglipat →
