| Feature | DeepClean | Delve |
|---|---|---|
| Best fit | Mac users who want explained cleanup categories and developer-cache coverage. | Apple Silicon users on macOS 26+ who want two maps and staged cleanup. |
| Visualization | Category and large-file lists with safety ratings | Treemap, sunburst, and file list |
| Platforms and requirements | macOS 13+ | macOS 26+, Apple Silicon |
| Pricing and editions | Free scan and first gigabyte of cleanup; unlimited cleanup listed at $39 once per Mac. | Vendor lists $4.99 once after a 14-day trial. |
| Open source | No | No |
| Native macOS UI | Yes | Yes |
| Cleanup workflow | Select items for Trash; caution items require deliberate selection and acknowledgement. | Stage items in the Collector, then send the reviewed batch to Trash. |
| Reports and portability | Retain deletion history and important decisions separately. The product overview does not document importing its records into another analyzer. | The developer documents exporting maps as posters with Command-Shift-E. Keep that image as a reference; it is not a scan file that NullDisk can import. |
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
Delve: what stands out
A good fit for Apple Silicon users on macOS 26+ who want two maps and staged cleanup.
Delve: strengths
- Treemap, sunburst, and file list
- Logical and on-disk measurement with filtering
- Quick Look, collector-to-Trash, and map image export
Considerations
- Requires macOS 26 or later
- Apple Silicon only in the current requirements
- A map export is a visual record, not a file backup
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 Delve?
A good fit for Apple Silicon users on macOS 26+ who want two maps and staged cleanup. Vendor lists $4.99 once after a 14-day trial.
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.
