| Feature | DissectMac | Space Radar |
|---|---|---|
| Best fit | People who want free inspection and optional paid app/leftover cleanup. | Developers exploring alternative visualizations and an inspectable codebase. |
| Visualization | Treemap and search | Sunburst, treemap, and flamegraph |
| Platforms and requirements | macOS (Intel and Apple Silicon builds) | macOS, Windows, Linux (check current packages) |
| Pricing and editions | Map, search, and monitor are free; Pro is listed at $12.99 once plus tax. | Free under the MIT license; check repository build/release instructions. |
| Open source | No | Yes |
| Native macOS UI | Yes | Cross-platform interface |
| Cleanup workflow | Pro moves selected files and app leftovers to Trash after review. | 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 overview does not establish scan-report export. Preserve any app-removal decisions and rescan the same folders in NullDisk. | Consult the exact build’s save/export controls. Keep any generated data and images; NullDisk does not document importing Space Radar sessions. |
DissectMac: what stands out
A good fit for people who want free inspection and optional paid app/leftover cleanup.
DissectMac: strengths
- Free map, file search, and live monitor
- Filters for developer files and large storage categories
- Pro uninstaller and app-leftover cleanup
Considerations
- In-app clearing and uninstallation require Pro
- Treemap is the documented graphical view
- Confirm suspected leftovers belong to apps you no longer need
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 DissectMac?
A good fit for people who want free inspection and optional paid app/leftover cleanup. Map, search, and monitor are free; Pro is listed at $12.99 once plus tax.
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.
