- Smaller feature surface than all-in-one suites
자주 묻는 질문
What is the best alternative to Delve for Mac?
For most Mac users it's NullDisk: native SwiftUI, a radial sunburst map, a staged removal collector, and zero data collection. Delve users who want mixed views and paid pricing will feel at home within minutes.
Is there a free alternative to Delve?
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 Delve to NullDisk?
Note the largest folders Delve flagged, then run the same scan in NullDisk and rebuild the cleanup in its removal collector. The full walkthrough is on our switching guide.
요약
Delve is a capable tool for mixed 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. 전환 가이드 →
