| Feature | Diskaroo | Space Radar |
|---|---|---|
| Best fit | Users wanting one account-based analyzer across Mac, Windows, and Linux. | Developers exploring alternative visualizations and an inspectable codebase. |
| Visualization | Treemap, sunburst, largest-items list, and duplicates | Sunburst, treemap, and flamegraph |
| Platforms and requirements | macOS 14+, Windows 10/11 x64, Linux x64 | macOS, Windows, Linux (check current packages) |
| Pricing and editions | Vendor currently offers lifetime Pro free with a Bravely Account; sign-in is required. | Free under the MIT license; check repository build/release instructions. |
| Open source | No | Yes |
| Native macOS UI | Cross-platform interface | Cross-platform interface |
| Cleanup workflow | Confirmed collector action: Trash/Recycle Bin or permanent deletion. Duplicates use Trash/Recycle Bin. | The project documents context-menu actions to locate, open, and delete files or directories; confirm recovery behavior in the selected build. |
| Reports and portability | The vendor describes recent locations, not an interoperable report format. Preserve paths and collector selections separately before rescanning. | Consult the exact build’s save/export controls. Keep any generated data and images; NullDisk does not document importing Space Radar sessions. |
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
Space Radar: what stands out
A good fit for developers exploring alternative visualizations and an inspectable codebase.
Space Radar: strengths
- Sunburst, treemap, and flamegraph visualizations
- MIT-licensed source for inspection and modification
- Disk and memory visualization in one project
Considerations
- Packaging and dependencies vary across repository versions
- Check the current release for your OS and CPU
- Do not infer cleanup or report formats from the chart selection
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 Space Radar?
A good fit for developers exploring alternative visualizations and an inspectable codebase. Free under the MIT license; check repository build/release instructions.
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.
