DaisyDisk Alternatives for Mac: Free and Paid
Short answer: DaisyDisk is still the default Mac disk map for a reason: a fast, beautiful sunburst for $9.99 once across five Macs, with a free trial. The best free alternative is GrandPerspective (treemap, open source, still updated). For a Terminal tool, use ncdu. For more features in one paid app, DiskBuddy. If you want a map that never deletes and tells you which app should clear each thing, there’s FavTray Space.
TL;DR
- Free and open source: GrandPerspective, or ncdu in Terminal.
- Free, simplest: OmniDiskSweeper, though it looks unmaintained.
- More in one app (duplicates, app footprints, snapshots, Windows): DiskBuddy.
- Already paying for CleanMyMac: its Space Lens is a similar bubble map.
- Read-only, developer-aware: FavTray Space, Pro.

What makes DaisyDisk good?
DaisyDisk from Software Ambience has been around since 2008, and version 4.34.2 shipped in July 2026. You pick a disk, it scans in seconds, and you get a sunburst: rings of folders you click into, with sizes that make the big ones obvious. Drag anything into the collector at the bottom, review it, and delete. It handles hard links correctly, shows APFS snapshots, has an admin scan for hidden folders, previews files, and can scan cloud storage such as Dropbox, Google Drive, OneDrive and Box.
It’s $9.99 once for up to five of your own Macs, it’s on the App Store and sold directly, and it has a free trial. There isn’t much to complain about. People look for alternatives mostly because they want something free, open source, or with a different view.
Is GrandPerspective as good as DaisyDisk?
It’s plainer, and for many people just as useful. GrandPerspective draws a treemap: every file is a rectangle sized by how much space it takes, grouped by folder. Treemaps are denser than sunbursts, so you can see thousands of files at once, and colouring by extension or age makes patterns jump out (a wall of video files, a block of old downloads). It can delete from the view, and you can filter what it shows.
It’s free under the GPL, or $2.99 on the App Store for the same app. It’s still maintained: version 3.8.1 came out on 13 September 2026 and needs macOS 14 (older builds support older macOS).
What about ncdu and OmniDiskSweeper?
ncdu is the Terminal answer: brew install ncdu, then ncdu ~ gives you a list of folders by size that you move through with the arrow keys. It’s fast, works over SSH, and only deletes if you press d and confirm. If you prefer plain commands, du -sh ~/* | sort -h does the first step.
OmniDiskSweeper from the Omni Group is free and does the same thing with a window: folders sorted by size, drill in, trash what you don’t need. The newest build Omni lists has a macOS 10.12 minimum and there’s no recent release, so we’d treat it as a legacy tool.
Is DiskBuddy or CleanMyMac a better upgrade?
DiskBuddy is the newer all-in-one: eight views (including a treemap, flame and an age map), byte-level duplicates, app footprints, scan snapshots, compression and a system monitor, with cleanup staged before anything goes to the Trash. It’s $19 at launch, then $49, and runs on Windows too. We compared it in DiskBuddy alternatives.
CleanMyMac includes Space Lens, a bubble map of your disk that MacPaw rebuilt in CleanMyMac 5. It’s good, but it comes inside a subscription cleaner. If you only want the map, that’s a lot to pay for. See CleanMyMac alternatives.
Where does FavTray Space fit?
Full disclosure: FavTray is our app. Space makes a different choice from everything above: it never deletes, moves or changes a file. The actions it gives you are Reveal in Finder, Copy path, Quick Look, Open and Show in Terminal (which opens Terminal at that folder and runs nothing).
Why that’s useful: on a developer’s Mac, most of the disk is things another app owns: Xcode DerivedData and simulators, node_modules, package caches, the Docker or OrbStack disk image, Ollama models. Deleting those from a disk map works, sometimes, but the owning app knows how to do it safely. So Space:
- names what’s inside with rules for about 115 kinds of folder,
- ranks it in Worth a look by size and by how easily it comes back (DerivedData rebuilds itself; your Xcode Archives can’t be replaced, so they’re never offered),
- and opens the owner (Xcode, Docker Desktop, Steam, System Settings › Storage and others) at the right screen.
It also has a treemap you can switch between size, file count, age and recovery tier, a history that shows what grew and forecasts when the disk fills, duplicates over 50 MB, and every mounted volume or any folder.
What it doesn’t have that DaisyDisk does: a sunburst, a delete button, cloud drive scanning, or support for macOS before 14.
Price: Pro, $4.99 once during launch ($9.99 after 8 October 2026), with 7 days of Pro free on every install. Free shows your capacity, the recoverable total and a blurred map. Space arrives in FavTray 2.0.2.

Frequently Asked Questions
What is the best free alternative to DaisyDisk?
GrandPerspective. It's free and open source (GPL), draws a treemap of any drive or folder, colours files by type or age, and is still updated: version 3.8.1 came out in September 2026 for macOS 14 and later. It's also $2.99 on the Mac App Store if you'd rather install it from there.
Is there an open-source DaisyDisk alternative?
Yes: GrandPerspective (GPL) for a treemap, and ncdu in Terminal (install it with Homebrew) for a navigable list of folders by size. Both are free.
Is DaisyDisk safe?
Yes. DaisyDisk only deletes what you drag into its collector and confirm, and it protects system files. As with any disk tool that deletes, check what's in the collector before you empty it.
How much does DaisyDisk cost?
$9.99 once, for up to five personal Macs, with a free trial and a 30-day money-back guarantee. It's sold on the Mac App Store and directly.
Which disk analyzer for Mac doesn't delete anything?
FavTray Space is read-only: it never deletes, moves or changes a file. It maps the disk, ranks what's worth clearing by size and by how easily it comes back, and opens the app that owns the data so you clear it there. It arrives in FavTray 2.0.2 as part of Pro. du and ncdu in Terminal also only measure unless you tell ncdu to delete.
Does DaisyDisk need Full Disk Access?
To see everything, DaisyDisk offers an admin scan that reveals hidden and protected folders. Without it, some space shows up as hidden rather than broken down.
