| Feature | Disk Xray | Space Radar |
|---|---|---|
| Best fit | Mac users seeking an analyzer plus duplicate and photo cleanup tools. | Developers exploring alternative visualizations and an inspectable codebase. |
| Visualization | Sorted folder breakdown and cleanup lists | Sunburst, treemap, and flamegraph |
| Platforms and requirements | macOS 10.13+ (vendor requirements) | macOS, Windows, Linux (check current packages) |
| Pricing and editions | Free App Store download; full functionality via subscription or lifetime purchase. The subscription includes a seven-day trial. | Free under the MIT license; check repository build/release instructions. |
| Open source | No | Yes |
| Native macOS UI | Yes | Cross-platform interface |
| Cleanup workflow | Review each module’s action; ordinary cleanup and permanent shredding have different recovery implications. | 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 product page does not document scan export. Keep duplicate decisions and paths separately; hard-link accounting in NullDisk is not duplicate-content detection. | Consult the exact build’s save/export controls. Keep any generated data and images; NullDisk does not document importing Space Radar sessions. |
Disk Xray: what stands out
A good fit for Mac users seeking an analyzer plus duplicate and photo cleanup tools.
Disk Xray: strengths
- Size-sorted folder scanner
- Byte-by-byte duplicate checks and similar-picture search
- App uninstaller, disk cleaner, and optional file shredder
Considerations
- Six modules serve different cleanup tasks
- Shredder operations are permanent
- Vendor limits content overwriting to supported HDDs, excluding SSD/APFS/network drives
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 Disk Xray?
A good fit for Mac users seeking an analyzer plus duplicate and photo cleanup tools. Free App Store download; full functionality via subscription or lifetime purchase. The subscription includes a seven-day trial.
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.
