CleanMyMac alternatives for developers in 2026

What a developer's Mac fills up with, and which tool sees it: disk maps, build folder cleaners, Xcode tools and cleaners made for coding agents.

At a glance

CleanMyMac is a good general cleaner: system junk, an app uninstaller, malware scanning and app updates in one place. Developers tend to look elsewhere for a different reason. Most of their used space isn't system junk at all. It's package caches, build folders, simulators and, more and more, the data coding agents keep. A general cleaner sees these as large folders. The tools below each see one part of that picture better.

What a general cleaner misses

The measurement above is from one developer's Mac. None of those folders is junk in the usual sense. Each one is a cache a tool fills on purpose and can fill again, at a cost:

• npm and uv download packages again when they need them. Cheap.
• Projects installed with pnpm share files with its store, so deleting the store frees less than its size suggests.
• Hugging Face models can be many GB each and take a long time to download again.
• A git worktree looks like any project folder, but it may hold work that exists nowhere else.

The useful question isn't "is this folder big" but "what happens if it goes". That's where the alternatives differ.

MacPaw now has a command-line tool for developers too. CleanMyMac CLI, in public beta since July 2026, has clean dev for developer caches, purge for build folders and clean ai for junk from AI tools such as Claude Code and Codex. If you like CleanMyMac and work in a terminal, try that first. Its docs don't mention git worktrees, running agent sessions or undo.

DaisyDisk: see first, decide yourself

DaisyDisk draws your disk as a map, so you can see in seconds which folder grew. It costs $9.99 once and shows "hidden space" like purgeable space and snapshots. It knows nothing about developer folders: it shows node_modules and a worktree the same way, and you decide. What you delete goes away permanently, with a five-second window to cancel. Pick it when you want to look, not when you want a verdict.

DevCleaner for Xcode: only Xcode, but deeply

DevCleaner is free on the Mac App Store and cleans what Xcode leaves in ~/Library/Developer: Device Support, Archives, DerivedData, the documentation cache and old logs. It has a command-line tool and a dry-run setting. It deletes permanently and doesn't look at anything outside Xcode. If Xcode is where your space goes, it's the most focused tool here.

npkill and kondo: build folders from the terminal

npkill lists node_modules folders and deletes the ones you pick with rm -rf. kondo does the same for 24 project types, from Cargo to Unity, and can skip recent projects with --older. Both are free, open source and run on macOS, Linux and Windows. Both go by folder name and delete for good. See Devbroom vs npkill and Devbroom vs kondo for how that compares with checking evidence first.

Mole and Broomkit: developer cleaners

Mole is a free, open source command-line cleaner with a purge command for build folders like node_modules, target and dist. It leaves folders with file activity in the last 7 days unselected, and protects folders with git-tracked files. Most of its cleanup is permanent once you confirm. Its makers also sell a native app, Mole for Mac, for $19 once for two Macs.

Broomkit is a paid Mac app for developer caches and build folders: node_modules, pnpm, pip, DerivedData, simulators and Docker. It needs no account and is sold as a one-time payment.

Devbroom: for Macs where coding agents work

Devbroom is built for one situation: Claude Code, Codex, Cursor, OpenCode or Orca work across your projects and leave sessions, scratch folders, worktrees and build folders behind. It knows each agent and its rules, and gives every item a verdict, Ready, Review, Blocked or Unknown, with the reasons beside it. A worktree with uncommitted changes is Blocked, and so is a folder an agent session or process still uses. The rules are in Rules and what each verdict means is in Verdicts.

Cleaning moves items to the Trash, and Put back returns them from History. Your agents can ask Devbroom before they delete a folder themselves, through its MCP server; see Integrations. Scanning, cleaning, undo, the command line and MCP are free. Pro is $29 once, see Pricing.

When CleanMyMac is still the better pick

If you want one app for the whole Mac, with malware scanning, an uninstaller and app updates, none of the tools above replaces CleanMyMac. Plenty of developers keep it for that and add a developer tool for their own folders. The head-to-head is on Devbroom vs CleanMyMac.
