Nektony Disk Space Analyzer Pro: what stands out

A good fit for people who prefer an upfront App Store purchase with visual analysis and collections.

Nektony Disk Space Analyzer Pro: strengths

  • Sunburst, largest-items list, and Quick Look
  • Collect items for moving or removing
  • Scans external storage and accessible cloud folders

Considerations

  • Paid edition distinct from the free-download listing
  • Access depends on macOS permissions and chosen scan locations
  • A cloud-folder scan is not proof of direct provider-account access

SquirrelDisk: what stands out

A good fit for people wanting a free open-source GUI across desktop systems and remote storage.

SquirrelDisk: strengths

  • Live maps and a staged removal collector
  • Content-based duplicate search
  • SSH and rclone-backed cloud storage

Considerations

  • Uses a cross-platform Rust interface rather than SwiftUI
  • Permanent deletion and secure erase require deliberate review
  • Cloud/SSH actions depend on provider and remote-system support

Common questions

When should I choose Nektony Disk Space Analyzer Pro?

A good fit for people who prefer an upfront App Store purchase with visual analysis and collections. US Mac App Store lists $19.99 upfront; check your region’s current listing.

When should I choose SquirrelDisk?

A good fit for people wanting a free open-source GUI across desktop systems and remote storage. Free; AGPL-3.0 source published on GitHub.

Will both apps show the same size?

Not necessarily. Match the scan root, permissions, exclusions, and logical/allocated-size mode. Hard links, APFS clones, snapshots, sparse files, and cloud placeholders can change totals. A reported size is not a guaranteed amount recovered after deletion.
