Disk Graph

Pie-chart and treemap inspector with snapshots and search.

＋ Disk Graph: 強み

  • Multiple views: pie charts, treemaps, and file search
  • Snapshots let you compare disk usage over time
  • Universal purchase across Mac, iPhone, and Vision Pro

－ Disk Graph: 弱み

  • Jack-of-views approach means no single standout visualization
  • Cleanup workflow is thinner than dedicated cleaners
  • Smaller user base means fewer guides and comparisons

SpacePeek

A read-only Quick Look inspector for folders and archives.

＋ SpacePeek: 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

－ SpacePeek: 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

Choose Disk Graph if you want mixed visualization on macOS + iOS. Choose SpacePeek if you prefer list views at freemium pricing on macOS. And if you want a native Mac sunburst with a staged collector and zero telemetry, NullDisk is the third option that beats both on workflow.
