| Platforms and requirements | macOS, Windows, Linux (check current packages) | macOS |
| Pricing and editions | Free under the MIT license; check repository build/release instructions. | Part of CleanMyMac; check current subscription/one-time plans and edition availability. |
| Open source | Yes | No |
| Native macOS UI | Cross-platform interface | Yes |
| Cleanup workflow | The project documents context-menu actions to locate, open, and delete files or directories; confirm recovery behavior in the selected build. | Add selections to the cleanup list, review them, then run the module’s removal action. |
| Reports and portability | Consult the exact build’s save/export controls. Keep any generated data and images; NullDisk does not document importing Space Radar sessions. | Keep screenshots and paths from Space Lens. The cited manual does not establish report interoperability with NullDisk. |
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
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
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.
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.
