Pros & cons
＋ 강점
- Beautiful bubble-map view distinct from sunbursts and treemaps
- One click from analysis to automated cleanup inside the suite
- Backed by MacPaw's large support and update operation
－ 약점
- Requires the full CleanMyMac suite — no standalone purchase
- Subscription push where single-purpose rivals charge once
- Suite scope means deeper scans can feel like an upsell path
자주 묻는 질문
What is the best alternative to SpaceLens for Mac?
For most Mac users it's NullDisk: native SwiftUI, a radial sunburst map, a staged removal collector, and zero data collection. SpaceLens users who want mixed views and paid pricing will feel at home within minutes.
Is there a free alternative to SpaceLens?
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 SpaceLens to NullDisk?
Note the largest folders SpaceLens 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
SpaceLens 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 →
