| Feature | diCleaner | Space Radar |
|---|---|---|
| Best fit | Mac users seeking free storage analysis alongside broader maintenance tools. | Developers exploring alternative visualizations and an inspectable codebase. |
| Visualization | Storage overview, file categories, and maintenance lists | Sunburst, treemap, and flamegraph |
| Platforms and requirements | macOS 11.5+ | macOS, Windows, Linux (check current packages) |
| Pricing and editions | Vendor says free to use with all current features included. | Free under the MIT license; check repository build/release instructions. |
| Open source | No | Yes |
| Native macOS UI | Yes | Cross-platform interface |
| Cleanup workflow | No automatic deletion after scanning; most tools use Trash by default. Secure Remove and Trash emptying are permanent. | 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 cited pages do not establish scan-report export. Keep any important history or paths before rescanning; retain the original files until decisions are verified. | Consult the exact build’s save/export controls. Keep any generated data and images; NullDisk does not document importing Space Radar sessions. |
diCleaner: what stands out
A good fit for Mac users seeking free storage analysis alongside broader maintenance tools.
diCleaner: strengths
- Storage analysis, large/old files, and duplicate/similar-photo tools
- App uninstallation, leftovers, and startup-item review
- Selection-based cleanup with Trash defaults for most tools
Considerations
- Permanent removal and privacy tools have different effects from Trash
- App Store privacy disclosure lists some non-linked data
- Cleanup eligibility depends on files, apps, and permissions
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 diCleaner?
A good fit for Mac users seeking free storage analysis alongside broader maintenance tools. Vendor says free to use with all current features included.
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.
