Best DaisyDisk alternatives for Mac in 2026, free and paid
Short answer. The best free DaisyDisk alternative is GrandPerspective, an open-source treemap. Klarity Disk ($6.99) is a cheaper paid map, and Nektony's Disk Space Analyzer is free to look and paid to remove files. If you'd rather have a plain list, OmniDiskSweeper sorts everything largest first. If you want cleanup and maintenance too, there's CleanMyMac or Mole. DiskFox, which we make, is the one to try if your storage keeps filling up and you want to know what grew and when.
We make DiskFox, so weigh our view accordingly. Every price and feature below comes from the maker's own pages, linked in each section, and was checked in October 2026. Where we didn't find something on those pages, we say "not advertised": the app may still do it.
What DaisyDisk does well
DaisyDisk draws your disk as colourful rings you click into. Its site says it works with internal, external and network disks, can show hidden space with a scan as administrator, explains System Data and detects macOS snapshots. It's $9.99 one-time, with a free trial download, from its website or the Mac App Store, and needs macOS 10.13 or later.
If that's what you need, it's hard to beat. People usually look elsewhere for one of these reasons:
- They want something free. DaisyDisk's trial is free, but the app is $9.99 to keep.
- They find rings hard to read and want rectangles (a treemap) or a plain list.
- They want more than a map, such as cleanup suggestions, an uninstaller or duplicate finding.
- Their storage keeps filling up and a picture of today doesn't say what changed since last week.

The alternatives
GrandPerspective: the free one
GrandPerspective draws a treemap: each file is a rectangle whose area matches its size. It's open source under the GNU GPL, and you can save a scan and reopen it later. Version 3.8.1 (13 September 2026) needs macOS 14 or later.
Compared with DaisyDisk: rectangles instead of rings, and free. It's a viewer first: you find the big files in it, then deal with them in Finder.
Price: free from SourceForge, or $2.99 on the Mac App Store; its site says it's the same app either way. Sources: GrandPerspective, App Store.
Klarity Disk: a cheaper paid map
Klarity Disk has treemap and icicle views. Its site says it's "100% local", with no network connections, accounts or analytics. It moves files to the Trash, asks you to confirm before removing anything 1 GB or larger, and protects system folders.
Compared with DaisyDisk: a few dollars cheaper, with different map shapes. It needs a newer Mac: macOS 14.6 or later.
Price: $6.99 one-time. Source: klaritydisk.com.
Nektony's Disk Space Analyzer: rings for free
Called "Disk Space Analyzer: Inspector" on the Mac App Store, it draws a sunburst diagram, the closest look to DaisyDisk here, and also has a folder treemap. The free version shows the map and the 8 biggest items; Pro adds removing and moving files.
Compared with DaisyDisk: a similar picture at no cost, as long as you only want to look. Removing files from inside it means paying, and Pro is sold monthly, yearly or once. It needs macOS 11 or later.
Price: Pro is $4.99 a month, $9.99 a year or $19.99 lifetime on the App Store; Nektony's own site says "from $4.95/mo". Sources: nektony.com, App Store.
OmniDiskSweeper: a list, not a map
OmniDiskSweeper lists what's on your drive from largest to smallest, and lets you open items or move them to the Trash.
Compared with DaisyDisk: no picture at all. Some people find a sorted list quicker to act on. Omni doesn't say which macOS versions the current download supports, so check it runs on your Mac. Source: Omni Group.
CleanMyMac: a map inside a bigger suite
CleanMyMac from MacPaw covers cleanup, malware removal, speed tools, app updates and uninstalling. Its Space Lens feature draws your storage as bubbles, for an internal or external drive or a single folder.
Compared with DaisyDisk: far more than a disk map, and priced like it. Worth it if you want one app for general upkeep; a lot to pay for if you only want to see what's big.
Price: "Starting at $3.33/month", with yearly and one-time options and a 7-day free trial. A one-time licence doesn't include major upgrades. Sources: CleanMyMac, editions.
Mole: open source with cleanup
Mole is a free, open-source command-line tool (installed with Homebrew) with a separate paid Mac app. The app combines cleanup, an uninstaller, a treemap you can click into and live system stats. Its site says cache cleanup deletes permanently by default, with an option to use the Trash instead.
Compared with DaisyDisk: less polished as a map, but it also cleans. If you're comfortable in Terminal, the free tool may be all you need.
Price: the command-line tool is free; the app is $19 one-time for two Macs. Sources: mole.fit, GitHub.
DiskFox: when your storage keeps filling up
DiskFox keeps a dated history of each scan and tells you what changed, for example "Storage use grew by 92.6 GB this week", with each change labelled Cause when DiskFox measured it, or Likely cause when it's an inference, such as growth soon after a macOS update. Its storage map sizes blocks by space, like DaisyDisk's rings, and colours them by how much they grew this week. It also estimates what's inside System Data, lists your largest files, finds exact duplicates and shows apps with the data they keep. Cleanup is review-first, and most items go to the Trash.
Compared with DaisyDisk: it answers "what changed?" as well as "what's big?". It measures your startup disk and the external drives you switch on, but not network drives, and it only checks while it's open. It needs macOS 14 or later and is a direct download, not on the Mac App Store.
Price: a one-time purchase for up to two Macs, with every feature free for 14 days and no card needed. The full side-by-side is on DiskFox vs DaisyDisk.
Or use what's built into macOS
Before you download anything, Apple menu > System Settings > General > Storage shows a bar of categories and lets you review and delete large files, and Finder can search by file size. Our guides to finding what's taking up space and finding large files walk through both. If your free space keeps shrinking, tracking storage changes by hand shows how to see what grew without any app.
