Disk Space Analyzer alternative: Peekaboo vs Disk Space Analyzer
By Vishva Variya · Updated
Disk Space Analyzer from Nektony (“Inspector” on the App Store) draws your disk as a sunburst or treemap, scans external and network drives, and lists the largest files. The free App Store version shows the eight biggest items; deleting, moving and copying come with Pro. Peekaboo also maps the disk, and adds the part that comes after the map: deciding what to delete.

Why pick Peekaboo over Disk Space Analyzer?
A map that leads somewhere
Peekaboo’s Space Map is a clickable sunburst by category and folder, and Disk Usage lists every folder by size plus the space macOS frees on its own.
Suggestions, not just sizes
Clean Up groups duplicates, forgotten downloads, old installers, old screenshots, big old videos and unused apps, so you don’t have to judge each folder yourself.
Undo every cleanup
Files go to the Trash as a recorded session; one click puts them all back.

The honest verdict
If you need to map network drives, or only want a picture of the disk, Disk Space Analyzer’s free tier or $19.99 lifetime unlock is good value. If you want the map plus a list of what’s safe to clear and a way back if you clear the wrong thing, Peekaboo does both in one app.
