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.
