OmniDiskSweeper alternatives

Why people look for an OmniDiskSweeper alternative

OmniDiskSweeper is a small free tool from The Omni Group, the makers of OmniFocus. It lists everything on a drive in Finder-style columns, largest first, so you can drill down to what's big and open it or move it to the Trash. It has done that job for a long time. People who look for something else usually want one of these.

• A picture. There's no treemap, sunburst or chart, just the sorted columns.
• To know what a folder is. OmniDiskSweeper tells you a file's size. It can show which installer package a file came from, but it doesn't say what a folder is for, which app made it, or whether it's safe to remove.
• A review list. Actions apply to the selection straight away. There's no list of everything you've picked to check before it moves.
• No instant-delete shortcut. Items go to the Trash by default, but holding Option deletes immediately, skipping the Trash. Some people would rather that path didn't exist.
• Undo in the app. None is documented. Getting something back means using Put Back in Finder's Trash.

When OmniDiskSweeper is all you need

If you know what you're looking at and just want the biggest items in order, a sorted list is quick and clear. OmniDiskSweeper is free, runs on macOS 11 and later, is native on Apple silicon, handles network volumes, and can run as root with sudo to size folders your account can't read. Omni's release notes say scan information is used only to show results in the app.

How we chose

The first pick is free, for people who mainly want a picture. The others add something OmniDiskSweeper doesn't: a different chart, explanations, or cleanup suggestions with a review step. For each we noted the price and what happens to removed files, as of October 22, 2026, from the vendor's own pages.

We make MacClearings, the second pick, so read that section knowing who wrote it. There's also a side-by-side page: MacClearings vs OmniDiskSweeper.

GrandPerspective

GrandPerspective is the natural free step up from a list. It draws a treemap where each file is a rectangle sized to match, so large files stand out at a glance. You can color by type, folder, age or size, filter what's shown, save scans and reload them later, and analyze Time Machine backups. Version 3.8.1 came out on September 13, 2026.

• Price: free and open source under the GPL, from SourceForge, or $2.99 on the Mac App Store.
• Requirements: macOS 14 or later for 3.8. Version 3.7.2 is offered for macOS 11 to 13.
• Removed files: deleting is a preference you can turn off, limit to single files, or extend to folders, with an optional confirmation. Its help says a deleted folder moves to the Trash. No review list and no documented in-app undo.

MacClearings

We make MacClearings; it's a one-person app by Chris Williams. It answers the question OmniDiskSweeper leaves open: what is this folder, and can it go?

The Map draws any folder as a sunburst or treemap, with a list of its contents beside it. Select a folder and the inspector explains it from a field guide of about 220 entries: what it is, which app made it, whether it comes back, and what happens without it. Find searches everything scanned with kind, size and date filters. Suggestions groups what can go by kind, and Breakdown explains System Data and purgeable space.

• Price: $25 once, or $12.50 for the first 25 buyers. OmniDiskSweeper is free. See pricing.
• Requirements: macOS 15 or later, Apple silicon and Intel.
• Privacy: no account and no analytics in the app.
• Removed files: only ever moved to the Trash, with no shortcut around it. Items you pick are staged, listed on one review sheet, checked again just before they move, and then moved to the Trash. History has Undo and Put Back. MacClearings never empties the Trash, so the space comes back when you empty it. See the safety page.

DaisyDisk

DaisyDisk swaps the columns for an interactive sunburst you can drill into, and you drag what you want gone into a collector. Its stand-alone edition also breaks hidden space into purgeable space, other APFS volumes and local snapshots.

• Price: $9.99 once for up to 5 personal Macs, direct or on the Mac App Store.
• Requirements: macOS 10.13 or later for the direct edition.
• Removed files: deleted permanently, not moved to the Trash, with five seconds to cancel. Its guide says it can't restore deleted files.

DiskBuddy

DiskBuddy shows one scan eight ways, including a ranked list, a sunburst and a treemap. It adds a cleanup list, a duplicate finder, an uninstaller and a system monitor, and one license covers the Mac and Windows versions.

• Price: $19 for the first 400 copies, then $49; the page showed 37 left on October 22, 2026. One Mac at a time.
• Requirements: macOS 14 or later.
• Removed files: moved to the Trash by default, with Undo for the whole cleanup. Permanent deletion is a separate option with its own warning. Items apps rebuild, caches included, start ticked.

Mole for Mac

Mole for Mac's Analyze tool draws a disk treemap, with Move to Trash and Reveal in Finder, and it won't move protected folders. The app also cleans, uninstalls, runs maintenance tasks and monitors the system.

• Price: $19 once, and the license activates 2 Macs. Each paid tool works twice before you buy.
• Requirements: macOS 14 or later.
• Removed files: Analyze and uninstalls use the Trash. Cache cleanup is permanent by default unless you change a setting, and there's no undo command.
