| Open source | No | Yes |
| Native macOS UI | Cross-platform interface | Yes |
| Cleanup workflow | Confirmed collector action: Trash/Recycle Bin or permanent deletion. Duplicates use Trash/Recycle Bin. | Delete files or folders from the view; review selection and deletion preferences. |
| Reports and portability | The vendor describes recent locations, not an interoperable report format. Preserve paths and collector selections separately before rescanning. | Save the scan for reopening in GrandPerspective, or export text and images. NullDisk does not import GrandPerspective scan files; retain exports and rescan the same location. |
Diskaroo: what stands out
A good fit for users wanting one account-based analyzer across Mac, Windows, and Linux.
Diskaroo: strengths
- Treemap, sunburst, filters, and largest-items list
- Collector with Trash/Recycle Bin or explicit permanent removal
- Content-based duplicates; Quick Look on Mac
Considerations
- Requires an account before the first scan
- Current free offer depends on claiming Pro in the app
- Linux build requirements include GTK 4
GrandPerspective: what stands out
A good fit for people who want a free, inspectable treemap and reusable scan records.
GrandPerspective: strengths
- Configurable colors, masks, searches, and scan exclusions
- Quick Look, Finder integration, and file/folder deletion
- Save/reload scans and export text or images
Considerations
- Treemap rather than radial navigation
- Older macOS versions require an older release
- App Store updates can follow SourceForge releases later
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 Diskaroo?
A good fit for users wanting one account-based analyzer across Mac, Windows, and Linux. Vendor currently offers lifetime Pro free with a Bravely Account; sign-in is required.
When should I choose GrandPerspective?
A good fit for people who want a free, inspectable treemap and reusable scan records. Free from SourceForge; the same app is $2.99 in the US App Store.
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.
