# Tidy Mac vs GrandPerspective

GrandPerspective draws your Mac’s disk as a free treemap. Tidy Mac has a treemap too, and tells you what each block is and whether it’s safe to delete.

Updated October 2, 2026By the Tidy Mac team

The short version

Pick GrandPerspective if you want a free, no-frills treemap and you can tell what each file is yourself. Pick Tidy Mac if you want the map plus answers: System Data split into named parts, each item marked Safe to clear, Worth a look or Kept, and cleaning to the Trash with undo. It’s $9.99 once, for two Macs.
