Two different jobs
Mole for Mac is a maintenance suite in one window. Cleaning is one tab among several. The others cover an uninstaller, a treemap disk map, macOS maintenance tasks, live CPU, memory, and thermal readouts, app updates, startup items, and fan control on Macs that allow it. If you have used CleanMyMac, the shape is familiar, with a one-time price instead of a subscription.
Purge does one job. It scans a fixed allowlist of paths, labels each row Safe to Clean or Check First, and sends what you confirm to the Trash. Beyond caches it covers Xcode DerivedData and other developer junk, build artifacts, orphaned git worktrees left behind by AI coding tools, large files, duplicates, Ollama and LM Studio models, app leftovers, and older local Time Machine snapshots. It does not monitor anything, optimize anything, or update your other apps.
The difference that matters most in daily use is what happens after you click Clean. Mole for Mac deletes caches permanently by default and offers a Trash option in Settings. Purge puts files in the Trash and leaves emptying it to you. Simulator devices and confirmed snapshots are the two permanent exceptions, and the app says so on the row.
Who should pick which
Mole for Mac makes sense if you want cleanup, monitoring, app updates, and a disk map in one app, and $19 for a lifetime license on two Macs sounds fair. It is the broader tool, its uninstaller reaches further, and it comes from a project with a much larger community than Purge. Closed source is the trade. You cannot read what the Mac app is allowed to delete.
Purge makes sense if the problem is disk space, you want the deletion list in source you can read, and you would rather have a Trash to dig through than a permanent delete. It also has a few things Mole for Mac does not: a duplicate finder, Ollama and LM Studio model cleanup, an opt-in scheduled clean of Safe items, and a watcher that offers a leftover review after you drag an app to the Trash. It requires macOS 13 or later, one release older than Mole for Mac asks for.
If you live in the terminal, neither app is the answer. The Mole project ships a free command-line tool, covered below. Purge has no command-line version.
Side-by-side comparison
brew install mole, with --dry-run and --json.What Purge deliberately does not do
Calling Purge an alternative is not a claim to feature parity. Purge does not include:
- A treemap disk map
- macOS maintenance routines such as cache rebuilds or SQLite vacuums
- Live CPU, memory, GPU, or fan monitoring
- Updates for your other apps
- Startup item management
- Fan control
- An uninstaller that also clears Dock entries or input methods
If those matter, Mole for Mac is the better fit. If you mainly want space back from caches and a dev machine, and you want to see the allowlist before trusting it, Purge is built for that narrower job.
The free command-line tool
The confusion in a lot of "free Mole" searches is that there are two Moles. tw93/Mole is a free, GPL-3.0 command-line tool with about 70,000 GitHub stars. brew install mole installs that tool, not the Mac app. It cleans, uninstalls, optimizes, and analyzes from the terminal, with --dry-run on every destructive command and --json output on some. Mole for Mac is a separate native app that shares the tool's cleanup rules and sells for $19. This page compares Purge with the Mac app, because Purge is a graphical app and has no terminal equivalent.
How to try Purge alongside Mole
You can install Purge without removing Mole for Mac. They overlap on cache folders, so turn off scheduled cleaning in whichever one you are not actively using.
- Install Purge from the notarized build on GitHub releases, or with Homebrew:
brew install --cask jithin-sabu/tap/purge- Grant Full Disk Access when asked. App Caches and Dev Tools scan without it. Large Files and the uninstaller need it, granted in System Settings under Privacy & Security.
- Start with Safe to Clean for a conservative first pass, then read the Check First rows before ticking any of them.
- Empty the Trash yourself when you are satisfied. Purge shows what is still sitting there, so the free space figure is not a surprise.
FAQ
Is Mole for Mac free?
No. Mole for Mac costs $19 once for two Macs, with no subscription. Scanning is free, and each paid tool works twice before the app asks for a license. The command-line tool from the same project is free and open source under GPL-3.0, but it is a terminal program, not the Mac app.
Is the Mole Mac cleaner safe?
It is a widely used app from a large project, and it shows the full file list before it deletes anything. The part to know about is where files go. Mole for Mac deletes caches permanently by default, so there is no Trash to pull them back from unless you switch on the Trash option in Settings. Purge sends ordinary deletions to the Trash and never empties it. Removing iOS simulator devices and confirmed local Time Machine snapshots is permanent in Purge, and both are labeled that way.
Does Purge do everything Mole for Mac does?
No. Purge cleans disk space and uninstalls apps. It has no disk map, no maintenance routines, no live monitoring, no app updater, no startup item manager, and no fan control. If you want those in one window, Mole for Mac is the broader app and Purge is not a replacement for it.
Can I run Purge and Mole for Mac together?
Yes. They clean many of the same cache folders, so you will not gain much from running both, but nothing breaks. If you keep both, turn off scheduled cleaning in one of them so they are not clearing the same folders on different timers.
Does Purge have a command-line version?
No. Purge is a graphical app with no terminal command, dry-run flag, or JSON output. If you want to script cleanup, the Mole command-line tool is built for that and is free.
Try Purge
Purge is free and open source. If this comparison matches what you need, download it, run a scan, and read the safety labels before you clean anything.
