Disk Inventory X: what stands out
A good fit for users interested in the classic treemap or its community successors.
Disk Inventory X: strengths

- 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
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

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
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
When should I choose Disk Inventory X?
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 LumaDisk?
A good fit for Mac/Windows users wanting maps, duplicates, and build-cache discovery. Seven-day full trial; scanning stays free. Vendor lists $6.89 once for the remaining features.
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.
