LumaDisk: what stands out
A good fit for Mac/Windows users wanting maps, duplicates, and build-cache discovery.
LumaDisk: strengths
- Sunburst and treemap with live scan updates
- Build-cache radar, duplicate groups, and unused-file lists
- OneDrive/Dropbox connections; iCloud through its local folder
Considerations
- Verify Mac CPU support; current site highlights Apple Silicon
- Features beyond scanning require an unlock after trial
- Google Drive is listed as coming soon
Space Lens (CleanMyMac): what stands out
A good fit for existing CleanMyMac users who want visual disk exploration within their suite.
Space Lens (CleanMyMac): strengths
- Bubble visualization of local and external storage
- Folder-by-folder browsing and a reviewed removal list
- Part of the broader CleanMyMac maintenance suite
Considerations
- A suite module rather than a standalone purchase
- Check module availability in your CleanMyMac edition
- Suite licensing may be more than needed for disk analysis alone
For a useful comparison on your own drive, match the scan root, access permissions, and size mode. Chart style changes how you explore the results; it does not by itself establish measurement accuracy.

Will both apps show the same size?
Not necessarily. Match the scan root, permissions, exclusions, and logical/allocated-size mode. Hard links, APFS clones, snapshots, sparse files, and cloud placeholders can change totals. A reported size is not a guaranteed amount recovered after deletion.
