ClearDisk vs CleanMyMac vs DaisyDisk -- Best Mac Disk Cleaner (2025)

ClearDisk

Free -- MIT License -- Open Source

Menu bar app built with Swift/SwiftUI. Focuses specifically on developer caches that other cleaners miss entirely.

Pros:

• 100% free, no trials, no upsells, no subscriptions
• Open source -- you can audit exactly what it does
• Menu bar app -- always one click away, no window management
• Detects 15+ developer cache types (Xcode, npm, Docker, pip, CocoaPods, Cargo, SPM, Homebrew, etc.)
• Shows real-time sizes before you clean anything
• Install via Homebrew: brew tap bysiber/cleardisk && brew install --cask cleardisk
• Lightweight (~590 KB)

Cons:

• Requires macOS 14 (Sonoma) or later
• No disk space visualization (sunburst chart etc.)
• No malware scanning or system junk cleanup
• Developer-focused -- not for general system maintenance
• Relatively new project, smaller community

Best for: Developers who want a free, trustworthy tool that knows exactly where Xcode, Node.js, Docker, and other dev tools hide their caches.

CleanMyMac X by MacPaw

$40/year (1 Mac) -- $90/year (5 Macs) -- or $120 one-time

The most well-known Mac cleaner. All-in-one with system cleaning, malware scanning, app updates, and more.

Pros:

• Most comprehensive feature set -- cleaning, malware, updates, uninstaller
• Polished UI with disk visualization
• Cleans system caches, logs, mail attachments, Trash
• Apple-notarized, well-established company
• Good at finding general system junk

Cons:

• Expensive -- $40-90/year ongoing subscription
• Closed source -- you can't verify what it does or deletes
• Doesn't know about most developer caches (node_modules, Docker, pip, CocoaPods, Cargo)
• Aggressive upsell notifications
• Some Reddit users report it as "scamware" or unnecessary for tech-savvy users
• macOS already has built-in storage management (Apple menu -> About This Mac -> Storage)

Best for: Non-technical users who want a one-click solution and don't mind paying a subscription. Less useful for developers who need targeted cache cleanup.

DaisyDisk

$10 one-time -- Mac App Store or direct

Beautiful disk space visualizer with a sunburst chart. Scans your entire disk and shows what's taking space.

Pros:

• Best disk visualization -- interactive sunburst chart
• One-time purchase, no subscription
• Fast full-disk scan
• Drag-and-drop deletion
• Shows hidden files that Finder doesn't
• Apple Design Award winner

Cons:

• Doesn't know what developer caches are -- you have to find them manually in the chart
• No automated cleanup categories
• Scan-and-browse approach means you need to know what to look for
• Can't clean system-protected locations without admin privileges

Best for: Anyone who wants to understand where their disk space went. Excellent visual tool, but pairs well with a dev-specific cleaner like ClearDisk for targeted cleanup.

OnyX by Titanium Software

Free

Swiss army knife for macOS maintenance. Cleans system caches, runs maintenance scripts, tweaks hidden settings.

Pros:

• Free, well-respected, been around since Mac OS X 10.0
• Cleans system, user, and font caches
• Runs macOS maintenance scripts
• Verifies disk and system file integrity
• Tons of hidden macOS preferences tweaks

Cons:

• Looks dated, complex UI
• Not developer-focused -- doesn't know about Xcode, npm, Docker caches
• Must download the correct version for your exact macOS version
• Can be confusing for beginners
• No automatic detection of what to clean

Best for: Power users who want system maintenance tools beyond just disk cleanup. Not a replacement for dev-specific cache cleaning.

DevCleaner

Free -- Open Source -- Mac App Store

Focused exclusively on cleaning Xcode-related caches: DerivedData, Archives, Device Support, and documentation.

Pros:

• Free on the Mac App Store
• Open source
• Thorough Xcode cleanup (DerivedData, Archives, old simulators, documentation)
• Simple, focused UI

Cons:

• Xcode only -- doesn't touch node_modules, Docker, pip, Homebrew, CocoaPods, etc.
• Not a menu bar app -- needs to be launched manually
• If you don't use Xcode, this app is useless

Best for: iOS/macOS developers who only need Xcode cleanup. Consider ClearDisk if you also use Node.js, Docker, Python, or other dev tools.

Manual Terminal Cleanup

Free -- comes with macOS

You can clean everything manually with terminal commands. No app needed.

# Xcode DerivedData
rm -rf ~/Library/Developer/Xcode/DerivedData

# node_modules (find all, show sizes)
find ~ -name "node_modules" -type d -prune -exec du -sm {} \;

# Docker
docker system prune -a --volumes

# Homebrew
brew cleanup --prune=all

# pip
pip cache purge

# CocoaPods
pod cache clean --all && rm -rf ~/Library/Caches/CocoaPods

# npm cache
npm cache clean --force

Pros: Free, precise control, nothing to install

Cons: You need to remember 10+ different commands for different tools. No size preview. Easy to miss locations. Tedious to do regularly.

Best for: Developers comfortable with the terminal who want maximum control. Or use ClearDisk to see everything at once, then use terminal commands selectively.
