| Native macOS UI | Yes | Yes |
| Cleanup workflow | Select items for Trash; caution items require deliberate selection and acknowledgement. | Inspection and copying; use Finder or a separate cleanup tool for removals. |

DeepClean: what stands out
A good fit for Mac users who want explained cleanup categories and developer-cache coverage.
DeepClean: strengths
- Safe/Review/Caution categories and item explanations
- Developer toolchain cleanup and content-matched duplicates
- Trash-first cleanup with deletion history
Considerations
- Unlimited cleanup requires a paid per-Mac license
- Category judgments still depend on your workflow
- Primarily category-based cleanup rather than a disk map
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
For a useful comparison on your own drive, match the scan root, access permissions, and size mode. Chart style changes how you explore the results; it does not by itself establish measurement accuracy.
Common questions
When should I choose DeepClean?
A good fit for Mac users who want explained cleanup categories and developer-cache coverage. Free scan and first gigabyte of cleanup; unlimited cleanup listed at $39 once per Mac.
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.
