Delve / Comparisons
The familiar idea carries over: make large files visible, inspect their location, and decide what to keep. The app needs to fit macOS.
Khaos Studios makes Delve. This comparison draws on the official product documentation linked below.
WinDirStat’s official project is a Windows disk usage analyzer. It does not provide a macOS edition. For a Mac, choose a tool with published macOS support instead of treating a similarly named download as an official port.
If the treemap is what you liked, GrandPerspective is a free, open-source starting point. Delve offers a treemap and sunburst for Apple Silicon Macs on macOS 26 or later.
| What you want | Start with | Why |
|---|---|---|
| A free, open-source treemap | GrandPerspective | A configurable visual map with filters and saved scans |
| Treemap and sunburst views | Delve | Two perspectives on a scan, Quick Look, and a Collector |
| A simple size-sorted list | OmniDiskSweeper | File and folder browsing with open and Trash actions |
| A familiar Windows utility on Mac | WizTreeMac | An official macOS app is now available from WizTree’s developer |
| Connected cloud storage analysis | DaisyDisk | Direct connections to supported cloud accounts |
Delve offers a 14-day free trial, then $4.99 once or free access through referrals. GrandPerspective is free direct, with an optional paid App Store edition. WizTreeMac’s free license is for personal use; review the developer’s terms for commercial use.
Permissions can affect which folders an app can inspect. A scan that cannot read part of the disk should not be treated as a complete inventory. Use the app’s documented permission workflow when you need to inspect protected locations.
File size and recovered space are also different questions. Shared storage, snapshots, and items retained in the Trash can mean the free-space change differs from the size of selected files. Delve’s storage accounting notes explain the distinction.
For a built-in starting point, use our Finder and Storage settings guide.
Start with GrandPerspective for a free treemap. Try Delve if you want both visual layouts and a Collector on a compatible Mac. If you specifically used WizTree on Windows, its official Mac edition is worth evaluating before switching to a different product.
The official WinDirStat project provides a Windows application, not a macOS edition. Choose a native Mac alternative and download it from the developer’s official site.
For an open-source treemap, GrandPerspective is a useful starting point. Its direct download is free. OmniDiskSweeper is another free option if a sorted list suits you better.
Yes. The developer now offers WizTreeMac for macOS 12 or later. It is separate from WinDirStat and has its own licensing terms.
Delve has a 14-day free trial, then $4.99 once or free access through referrals. It requires macOS 26 or later on Apple Silicon.
