Who SquirrelDisk is for

Tinkerers, privacy purists, and anyone who wants an auditable tool. Fans of sunburst visualization on macOS + Windows + Linux. If instead you want a native Mac sunburst with a staged, Trash-based cleanup and zero telemetry, that's NullDisk's whole pitch.

Veelgestelde vragen

Is SquirrelDisk worth it?

SquirrelDisk is worth a look if you like sunburst views and open source pricing on macOS + Windows + Linux. The easiest open-source sunburst for hunting huge files. For a native Mac map with a staged cleanup workflow, compare it against NullDisk before deciding.

Is SquirrelDisk safe?

SquirrelDisk 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 SquirrelDisk work on Apple Silicon?

SquirrelDisk runs on macOS + Windows + Linux but isn't a native Mac app. If you want a fully native experience, NullDisk is Swift and SwiftUI end to end.

Kortom

SquirrelDisk: free and open source on every desktop OS — but java-based UI rather than native Mac controls. Weigh that trade honestly against NullDisk's native map, staged collector, and zero-data promise.
