Choose by workflow
GNOME’s disk usage analyzer for local devices, folders, and online accounts. If you need something different, compare these five options by the job they do. Choose by platform, features, and how you prefer to review files.
Mac users managing local/remote storage, and developers who need Git-aware cleanup or scriptable disk reports.
Mac/Windows users wanting maps, duplicates, and build-cache discovery.
Users wanting one account-based analyzer across Mac, Windows, and Linux.
People wanting a free open-source GUI across desktop systems and remote storage.
Developers exploring alternative visualizations and an inspectable codebase.

| Feature | Baobab (Disk Usage Analyzer) | NullDisk |
|---|---|---|
| Best fit | Linux desktop users who prefer a GNOME application with graphical disk analysis. | Mac users managing local/remote storage, and developers who need Git-aware cleanup or scriptable disk reports. |
| Visualization | Folder tree with ring/treemap graphical views | Radial map, treemap, and file list; CLI terminal treemap |
| Platforms and requirements | Linux (GNOME) | Mac app: macOS 14+; CLI: macOS, Linux, Windows |
| Pricing and editions | Free software from GNOME; available through Flathub/distributions. | Direct Mac edition free with reminders; optional $9.99 one-time personal license or team seat removes reminders. App Store terms are separate. |
| Open source | Yes | No |
| Native macOS UI | Linux application | Yes |
| Cleanup workflow | Inspect the selected location and use documented file actions or the system file manager. | Review source and action: local Trash, explicit permanent removal, or backup/delete; remote and cloud actions depend on the destination. |
| Reports and portability | Keep Baobab for Linux desktop analysis. For a terminal on Linux, NullDisk’s CLI can rescan the same filesystem; its Mac GUI does not import Baobab sessions. | CLI produces JSON/NDJSON scan reports. Third-party scan files are not directly imported into the Mac GUI. |
Keep Baobab for Linux desktop analysis. For a terminal on Linux, NullDisk’s CLI can rescan the same filesystem; its Mac GUI does not import Baobab sessions.
Linux desktop users who prefer a GNOME application with graphical disk analysis. Keep it if that matches your needs. Consider a change for a specific requirement such as a different chart, remote sources, report exports, or development cleanup.
GrandPerspective and SquirrelDisk offer free open-source analysis. OmniDiskSweeper is free on Mac. All direct Mac features in NullDisk are free with reminders; reminder removal is optional. Freeware does not necessarily mean open source.
No. Keep any historical exports you need and run a fresh scan of the same location. NullDisk does not import these apps’ saved scans or cleanup queues.
