Сильные стороны & Слабости
＋ Сильные стороны
- Free and open source with a tiny footprint
- Treemap rectangles make the single biggest space hog obvious
- Fast rescans and a loyal power-user community
－ Слабости
- Treemap UI is utilitarian — no sunburst, no guided cleanup
- No collector tray or duplicate finder; deletion is file-by-file
- Development pace is slow compared with commercial rivals
Who GrandPerspective is for
Tinkerers, privacy purists, and anyone who wants an auditable tool. Fans of treemap 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.
- A staged removal collector: queue suspects, review, then Trash everything together.
- Allocated-size measurement with hard-link dedup, so reclaimed space matches reality.

Частые вопросы
Is GrandPerspective worth it?
GrandPerspective is worth a look if you like treemap views and open source pricing on macOS. The tiny open-source treemap that shows your biggest files instantly. For a native Mac map with a staged cleanup workflow, compare it against NullDisk before deciding.
Is GrandPerspective safe?
GrandPerspective 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 GrandPerspective work on Apple Silicon?
Yes — GrandPerspective runs on modern Macs, including Apple Silicon. If nativeness matters to you, NullDisk is built SwiftUI-first for macOS 14 and up.
Итог
GrandPerspective: free and open source with a tiny footprint — but treemap UI is utilitarian — no sunburst, no guided cleanup. Weigh that trade honestly against NullDisk's native map, staged collector, and zero-data promise.
