－ Puntos débiles

- Aging codebase with infrequent updates
Who JDiskReport is for
Budget-conscious cleaners who want the job done without paying. Fans of charts visualization on Windows + Mac + Linux (Java). If instead you want a native Mac sunburst with a staged, Trash-based cleanup and zero telemetry, that's NullDisk's whole pitch.
The NullDisk alternative
- Truly native: Swift and SwiftUI on macOS, not a cross-platform toolkit.
- A radial sunburst map instead of lists or treemaps — see usage at a glance and drill in with a click.
- Fully offline with a published zero-data policy — nothing ever leaves your Mac.

Preguntas frecuentes
Is JDiskReport worth it?
JDiskReport is worth a look if you like charts views and free pricing on Windows + Mac + Linux (Java). Java statistics charts that find your most obsolete folders. For a native Mac map with a staged cleanup workflow, compare it against NullDisk before deciding.
Is JDiskReport safe?
JDiskReport is as safe as its workflow: it visualizes usage and deletes on your command. Whatever you choose, prefer tools that stage deletions or use the Trash — which is exactly how NullDisk's collector works.
Does JDiskReport work on Apple Silicon?
JDiskReport runs on Windows + Mac + Linux (Java) but isn't a native Mac app. If you want a fully native experience, NullDisk is Swift and SwiftUI end to end.
En resumen
JDiskReport: rich statistics: size, age, and file-type distributions — but java UI feels alien on a modern Mac. Weigh that trade honestly against NullDisk's native map, staged collector, and zero-data promise.
