| Feature | DeepClean | Space Radar |
|---|---|---|
| Best fit | Mac users who want explained cleanup categories and developer-cache coverage. | Developers exploring alternative visualizations and an inspectable codebase. |
| Visualization | Category and large-file lists with safety ratings | Sunburst, treemap, and flamegraph |
| Platforms and requirements | macOS 13+ | macOS, Windows, Linux (check current packages) |
| Pricing and editions | Free scan and first gigabyte of cleanup; unlimited cleanup listed at $39 once per Mac. | Free under the MIT license; check repository build/release instructions. |
| Open source | No | Yes |
| Native macOS UI | Yes | Cross-platform interface |
| Cleanup workflow | Select items for Trash; caution items require deliberate selection and acknowledgement. | The project documents context-menu actions to locate, open, and delete files or directories; confirm recovery behavior in the selected build. |
| Reports and portability | Retain deletion history and important decisions separately. The product overview does not document importing its records into another analyzer. | Consult the exact build’s save/export controls. Keep any generated data and images; NullDisk does not document importing Space Radar sessions. |
DeepClean: what stands out
A good fit for Mac users who want explained cleanup categories and developer-cache coverage.
DeepClean: strengths
- Safe/Review/Caution categories and item explanations
- Developer toolchain cleanup and content-matched duplicates
- Trash-first cleanup with deletion history
Considerations
- Unlimited cleanup requires a paid per-Mac license
- Category judgments still depend on your workflow
- Primarily category-based cleanup rather than a disk map
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 DeepClean?
A good fit for Mac users who want explained cleanup categories and developer-cache coverage. Free scan and first gigabyte of cleanup; unlimited cleanup listed at $39 once per Mac.
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.
