Strengths & Weaknesses
＋ Strengths
- Multiple views: pie charts, treemaps, and file search
- Snapshots let you compare disk usage over time
- Universal purchase across Mac, iPhone, and Vision Pro
－ Weaknesses
- Jack-of-views approach means no single standout visualization
- Cleanup workflow is thinner than dedicated cleaners
- Smaller user base means fewer guides and comparisons
Who Disk Graph is for
Fans of mixed visualization on macOS + iOS. 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
- Honest one-time purchase instead of subscriptions or gated tiers.
- Fully offline with a published zero-data policy — nothing ever leaves your Mac.
- A staged removal collector: queue suspects, review, then Trash everything together.

Frequently asked questions
Is Disk Graph worth it?
Disk Graph is worth a look if you like mixed views and paid pricing on macOS + iOS. Pie-chart and treemap inspector with snapshots and search. For a native Mac map with a staged cleanup workflow, compare it against NullDisk before deciding.
Is Disk Graph safe?
Disk Graph 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 Disk Graph work on Apple Silicon?
Yes — Disk Graph runs on modern Macs, including Apple Silicon. If nativeness matters to you, NullDisk is built SwiftUI-first for macOS 14 and up.
Bottom line
Disk Graph: multiple views: pie charts, treemaps, and file search — but jack-of-views approach means no single standout visualization. Weigh that trade honestly against NullDisk's native map, staged collector, and zero-data promise.
