Klarity Disk: what stands out
A good fit for Mac users who prefer rectangular views and age-based browsing.
Klarity Disk: strengths
- Treemap and icicle layouts with age-based colors
- Large Files list and hidden Library visibility
- Trash-only removal with extra confirmation for large folders
Considerations
- No sunburst in the documented view selection
- Age indicates modification history, not whether a file is unnecessary
- System-folder guards intentionally limit removal
OmniDiskSweeper: what stands out
A good fit for Mac users who prefer a free size-sorted browser to a chart.
OmniDiskSweeper: strengths
- Largest-first file and folder browsing
- Open items or move them to Trash
- Official downloads include versions for older Macs
Considerations
- Column browsing rather than a graphical disk map
- Check the download requirements for your macOS version
- The cited overview does not document saved reports or duplicate matching

Common questions
When should I choose Klarity Disk?
A good fit for Mac users who prefer rectangular views and age-based browsing. Vendor lists $6.99 once through the Mac App Store.
When should I choose OmniDiskSweeper?
A good fit for Mac users who prefer a free size-sorted browser to a chart. Free download from The Omni Group.
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.
