強み & 弱み
＋ 強み
- Read-only by design — it cannot delete anything, so it's extra safe
- Peeks inside folders and archives with Finder-style Quick Look
- Very cheap Pro unlock
－ 弱み
- Read-only means no cleanup workflow at all
- No sunburst or treemap overview of a whole drive
- Niche tool, not a full disk analyzer
Who SpacePeek is for
Fans of list visualization on macOS. 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
- A radial sunburst map instead of lists or treemaps — see usage at a glance and drill in with a click.
- Honest one-time purchase instead of subscriptions or gated tiers.
- Fully offline with a published zero-data policy — nothing ever leaves your Mac.

よくある質問
Is SpacePeek worth it?
SpacePeek is worth a look if you like list views and freemium pricing on macOS. A read-only Quick Look inspector for folders and archives. For a native Mac map with a staged cleanup workflow, compare it against NullDisk before deciding.
Is SpacePeek safe?
SpacePeek is as safe as its workflow: it deletes from ranked lists. Whatever you choose, prefer tools that stage deletions or use the Trash — which is exactly how NullDisk's collector works.
Does SpacePeek work on Apple Silicon?
Yes — SpacePeek runs on modern Macs, including Apple Silicon. If nativeness matters to you, NullDisk is built SwiftUI-first for macOS 14 and up.
まとめ
SpacePeek: read-only by design — it cannot delete anything, so it's extra safe — but read-only means no cleanup workflow at all. Weigh that trade honestly against NullDisk's native map, staged collector, and zero-data promise.
