Disk Inventory X: what stands out
A good fit for users interested in the classic treemap or its community successors.
Disk Inventory X: strengths
- Treemap visualization of disk usage
- Xs updates the original codebase for Apple Silicon
- Y is a separate Swift/SwiftUI rewrite
Considerations
- The original X, revival Xs, and rewrite Y are different apps
- Compatibility and features depend on the chosen build
- Check each project’s current release and signing instructions
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.
Common questions

A good fit for users interested in the classic treemap or its community successors. Original X is free under the GPL; Xs and Y are independent community projects.
When should I choose Space Lens (CleanMyMac)?
A good fit for existing CleanMyMac users who want visual disk exploration within their suite. Part of CleanMyMac; check current subscription/one-time plans and edition availability.
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.
