Space Lens (CleanMyMac): what stands out
A good fit for existing CleanMyMac users who want visual disk exploration within their suite.
Space Lens (CleanMyMac): strengths
- Bubble visualization of local and external storage
- Folder-by-folder browsing and a reviewed removal list
- Part of the broader CleanMyMac maintenance suite
Considerations
- A suite module rather than a standalone purchase
- Check module availability in your CleanMyMac edition
- Suite licensing may be more than needed for disk analysis alone
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 Space Lens (CleanMyMac)?
A good fit for existing CleanMyMac users who want visual disk exploration within their suite. Part of CleanMyMac; check current subscription/one-time plans and edition availability.
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.
