Strengths and considerations
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
How cleanup works
The project documents context-menu actions to locate, open, and delete files or directories; confirm recovery behavior in the selected build. Confirm each file’s path and purpose before removing it. Items in Trash still occupy storage until it is emptied.
How NullDisk compares
A native Mac disk analyzer with radial and treemap views, SSH/cloud sources, and development cleanup. Consider it for Git-aware development cleanup or a workflow spanning local, SSH, and cloud storage. The separate CLI provides terminal browsing and structured reports.
All direct Mac features are free with reminders; an optional one-time license removes them.
NullDisk has no content-based duplicate finder. Its Mac app sends anonymous usage telemetry; read the privacy policy if that affects your choice.
