Pontos fortes & Pontos fracos

＋ Pontos fortes

  • Three visualizations including a rare flamegraph view
  • Free and MIT-licensed for tinkering
  • Web-tech stack runs anywhere

－ Pontos fracos

  • Experimental project, not a supported product
  • No deletion workflow — visualization only
  • Requires comfort with GitHub releases and rough edges

Who Space Radar is for

Tinkerers, privacy purists, and anyone who wants an auditable tool. Fans of mixed 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.

Perguntas frequentes

Is Space Radar worth it?

Space Radar is worth a look if you like mixed views and open source pricing on macOS + Windows + Linux. Sunburst, treemap, and flamegraph views for disk nerds. For a native Mac map with a staged cleanup workflow, compare it against NullDisk before deciding.

Is Space Radar safe?

Space Radar 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 Space Radar work on Apple Silicon?

Space Radar 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.

Em resumo

Space Radar: three visualizations including a rare flamegraph view — but experimental project, not a supported product. Weigh that trade honestly against NullDisk's native map, staged collector, and zero-data promise.
