Preguntas frecuentes
What is the best alternative to LumaDisk for Mac?
For most Mac users it's NullDisk: native SwiftUI, a radial sunburst map, a staged removal collector, and zero data collection. LumaDisk users who want sunburst views and paid pricing will feel at home within minutes.
Is there a free alternative to LumaDisk?
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 LumaDisk to NullDisk?
Note the largest folders LumaDisk flagged, then run the same scan in NullDisk and rebuild the cleanup in its removal collector. The full walkthrough is on our switching guide.
En resumen
LumaDisk is a capable tool for sunburst fans on macOS + Windows. But if you want the whole job — see, stage, and safely remove — done natively on a modern Mac, NullDisk is the upgrade. Guía de cambio →
