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
SpacePeek: what stands out
A good fit for Finder users who want to inspect archives before extracting or deleting them.
SpacePeek: strengths
- Preview and search folders plus ZIP, 7z, and RAR archives
- Folder-size overview without background indexing
- Pro adds deeper navigation and copying archive members
Considerations
- An inspection companion rather than a full-drive cleanup utility
- Free browsing stops after the first child level
- Pro archive copying is limited to 100 MiB per file

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 SpacePeek?
A good fit for Finder users who want to inspect archives before extracting or deleting them. Free previews; optional $3.99 one-time Pro purchase in the US App Store.
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.
