DaisyDisk Alternatives for Mac

Why People Look Beyond DaisyDisk

DaisyDisk is a good app, and it is worth saying so up front. It runs natively on Apple Silicon and Intel, costs $9.99 once rather than every year, covers up to 5 personal Macs, and its interactive ring chart is the reason many people think of disk analyzers as something visual at all.

The search for an alternative usually comes from one of five specific wants:

• Free. You need to find what filled your disk once, and paying for a tool feels like too much for a single cleanup.
• Open source. You would rather run something whose code you can read.
• A treemap. Some people read nested rectangles more easily than rings, especially on drives with very deep folder trees.
• Windows too. DaisyDisk has no Windows version, so anyone with a PC at work or at home needs a second tool.
• More cleanup features. Developers in particular want regenerable build caches and duplicate files found for them, not just drawn.

Is DaisyDisk Free, and Is It Worth It?

DaisyDisk is not free. You can download a free trial, and the full version is $9.99 one-time, with a 30-day money-back guarantee. For a polished tool you will keep using, that is fair pricing, and plenty of people will not need anything more.

One detail matters if you decide to stay with it: where you buy it. The Mac App Store edition is sandboxed, which means it cannot scan as administrator and cannot reveal or purge hidden and purgeable space. The version sold directly by the developer does not have those limits, so if you buy DaisyDisk, the direct download is the better choice.

Free DaisyDisk Alternatives

GrandPerspective

GrandPerspective is the closest thing to a default answer. It is open source under the GPL, runs natively on Apple Silicon and Intel, and draws your drive as a treemap where each file is a block sized by how much space it takes. The current release needs macOS 14 or later; an older 3.7.2 build covers macOS 11 to 13. It is free from SourceForge, and the identical app costs $2.99 on the Mac App Store if you would rather pay to support the developer.

OmniDiskSweeper

OmniDiskSweeper, from the Omni Group, skips the chart entirely. It shows a sorted column browser, largest to smallest, with buttons to open or trash what you select. It is free and very easy to understand. Keep in mind it is a side project from the company's labs rather than one of its core products, so treat it as a focused utility rather than a full cleanup suite.

Disk Inventory X

Disk Inventory X was a popular free GPL treemap for years, but the official build has not been updated since version 1.3 in December 2019. It officially supports macOS 10.13 to 10.15 and is Intel only, so on an Apple Silicon Mac it runs through Rosetta. Community forks with native Apple Silicon builds exist, but they are unofficial.

WizTreeMac

WizTree is famous on Windows, and its official Mac version, WizTreeMac 1.00, arrived in September 2026. It needs macOS 12 or later, is a Universal app for Apple Silicon and Intel, and is free for personal use, with a paid Supporter Code for commercial use. It is downloaded directly rather than from the Mac App Store. We cover it in detail in our WizTree for Mac guide.

LumaDisk: A Sunburst With Cleanup Built In

LumaDisk is the option for people who like DaisyDisk's sunburst and want more done for them. It shows your whole drive as an interactive sunburst, and one click switches the same scan to a treemap. The chart draws while the scan is still running, alongside the largest finds so far and an estimate of the time left. Click a wedge to zoom in and use the breadcrumb trail to step back out.

The extras are where it differs most:

• Build-cache radar finds and groups regenerable developer folders such as node_modules, Rust target, .next, Xcode DerivedData and .gradle. It only lists folders that rebuild themselves.
• Duplicate finder groups copies with the one to keep already ticked, and always leaves one copy of each group.
• Unused files lists files of 100 MB or more that you have not opened in 6 months, 1 year or 2 years.
• Cloud drives: iCloud Drive, OneDrive and Dropbox are mapped, including cloud-only files that are not stored on the Mac.

Items you choose go into LumaDisk's own Bin first, and reclaiming them gives you a 10-second undo. Be aware that reclaiming deletes permanently rather than moving files to the Trash, and system folders can never be queued. It does not clean anything automatically; you decide what goes.

It is a native app built in Rust with GPUI, the GPU-accelerated stack behind the Zed editor, with no Electron. On the Mac it needs macOS 12 or later on Apple Silicon, so Intel Mac owners should look at DaisyDisk or GrandPerspective instead. Pricing is a one-time $6.89 for up to 5 Macs, with all future updates included and a 14-day refund window on direct purchases. There is a 7-day free trial of everything, and after it ends, scanning and the sunburst stay free. LumaDisk sends no file names, contents or scan results anywhere, and needs no account.

Side-by-Side Comparison

If You Also Use Windows

There is no DaisyDisk for Windows, and none of the free Mac tools above have a Windows build either, apart from WizTree, whose Mac and Windows versions share Supporter Codes. LumaDisk runs on Windows 10 or later, on both x86-64 and ARM64, from the Microsoft Store, with the same sunburst and build-cache radar. Our guide to DaisyDisk alternatives for Windows covers the PC side in full.

Which Should You Pick?

• You already own DaisyDisk and it does the job: keep it. If you bought the Mac App Store edition and need administrator scans or purgeable space, the direct version removes those limits.
• You want free and open source: GrandPerspective. Current releases run natively on Apple Silicon and Intel, and the treemap is clear.
• You want the simplest possible view: OmniDiskSweeper. A sorted list is often all a one-time cleanup needs.
• You use WizTree on Windows: try WizTreeMac for a familiar treemap, free for personal use.
• You are on an Intel Mac: DaisyDisk or GrandPerspective, since LumaDisk requires Apple Silicon.
• You are a developer, work across Mac and Windows, or want duplicates and cloud-only files mapped: LumaDisk, with a sunburst like DaisyDisk's plus build-cache, duplicate and unused-file views.
