SpareDiskSpareDisk vs DaisyDisk
DaisyDisk is the best-known disk space analyzer for Mac, and a good one. SpareDisk is a newer, lower-priced alternative that adds cleanup tools to the disk map. This page compares the two fairly, using DaisyDisk’s own website as of September 2026, so you can pick the one that fits.

Choose DaisyDisk if
- You want to scan the entire startup disk, including restricted system folders, as administrator.
- You need to find and purge local Time Machine snapshots.
- You want to map cloud storage such as Dropbox or Google Drive.
- Your Mac runs a version of macOS older than 15.
Choose SpareDisk if
- You want a disk map and the cleanup tools in one app: large files, old files, duplicates, uninstall, leftovers and developer caches.
- You would rather not grant Full Disk Access. SpareDisk is sandboxed and reads only the folders you add.
- You want to see both logical size and size on disk, so a 68 GB sparse disk image that uses 2 GB doesn’t mislead you.
- You want every removal reviewed and re-checked before anything moves to the Trash.
- You want the lower price: $4.99 once.
What they share
Both are native Mac apps with one-time prices and no subscription, both run on Apple silicon and Intel, and both make it easy to see at a glance which folders are largest. If what you mainly want is a map of your whole disk, either will do.
Questions
Is SpareDisk a good DaisyDisk alternative?

Is there a cheaper alternative to DaisyDisk?
SpareDisk costs $4.99 once. GrandPerspective is free from SourceForge, with a treemap and no cleanup tools.
Does SpareDisk need Full Disk Access like other disk analyzers?
No. SpareDisk is sandboxed and scans only the folders and drives you add.
