Clean developer caches, project artifacts, and disk clutter. Analyze storage and reclaim space — without leaving the Terminal.
🩷 Built and used daily by the CleanMyMac team on our own Macs🩷
Developer storage builds up across Docker, Xcode, package managers, project folders, and AI tools. CleanMyMac CLI brings those leftovers into one place, shows what can be removed, and leaves the final decision to you.
💡CleanMyMac CLI is currently in public beta. Commands and behavior may evolve as we improve the experience.
- Developer Cleanup: Clears caches, build artifacts, and system junk across common developer tools (see Commands)
- Artifact Purging: Removes old build artifacts using age-based selection
- Disk Analysis: Reports on disk usage to show what is consuming storage
- Interactive Review: Prompts for confirmation before deletion; protected system locations; cleanup logic shared with CleanMyMac
- Terminal-Based: Scriptable commands intended for command-line workflows
- Privacy Controls: No source code or personal files are uploaded; analytics can be disabled via configuration
- Optimization: Runs quick performance tasks from the command line
- macOS 11 or later, Homebrew
The formula lives in our tap — MacPaw/homebrew-taps
brew install --cask macpaw/taps/cleanmymac-cliVerify the installation:
cleanmymac --versionThen launch the interactive interface:
cleanmymacOr start by analyzing what is taking up space:
cleanmymac analyze! Both cleanmymac and cmm run the same tool.

Find removable files created by developer tools, package managers, Xcode, AI tools, and macOS:
cleanmymac cleanScan a specific cleanup category:
cleanmymac clean dev
cleanmymac clean junk
cleanmymac clean ai
cleanmymac clean trashCleanMyMac CLI can detect caches and generated files from tools including: Homebrew, npm, Yarn, and pnpm, pip, Poetry, and uv, Xcode DerivedData, Device Support, Module Cache, and other Xcode-related files, supported AI-tool artifacts etc
You review detected items before cleanup.
Development projects accumulate generated files that can take gigabytes of disk space: node_modules, .next, .turbo, target, .build etc
Find them across common project folders:
cleanmymac purgeOr scan a specific directory:
cleanmymac purge ~/ProjectsResults are grouped by project so you know what each artifact belongs to.
Artifacts older than seven days are preselected. Newer artifacts remain visible but unchecked for manual review.
Tip
Use clean for shared caches and tool-generated junk.
Use purge for removable dependencies and build artifacts stored inside project folders.
Not sure where your disk space went?
Open the interactive storage analyzer:
cleanmymac analyzeOr start from a specific folder:
cleanmymac analyze ~/ProjectsNavigate through directories by size, explore what is consuming storage, and reveal items in Finder.
Browsing through the analyzer does not modify your files. Any removal action requires an explicit selection and confirmation.
Tip
If your Mac is running out of storage and you are not sure what is safe to remove, start with cleanmymac analyze.
Run lightweight maintenance tasks directly from Terminal:
cleanmymac optimizeOr run them separately:
cleanmymac optimize ram
cleanmymac optimize purgeableoptimize ramreleases inactive memoryoptimize purgeableasks macOS to release disk space already marked as purgeable
These commands do not remove project source code or personal documents.
CleanMyMac CLI is designed around transparency and control.
Before cleanup, you can inspect what was detected and decide what should be removed.
Safety features include:
- Interactive review before cleanup
- Protected system locations excluded from cleanup
- Project-aware purging with age-based selection
- Ignore list for files and folders you always want protected
- Explicit confirmation before removal
- Cleanup detection based on logic shared with CleanMyMac
Protect a path permanently:
cleanmymac ignore add ~/Projects/important-projectView protected paths:
cleanmymac ignore listRemove a path from the ignore list:
cleanmymac ignore remove ~/Projects/important-projectWarning
--force skips interactive confirmation for supported cleanup commands and removes detected items immediately. Run the command without --force first and review what it finds.

For detailed examples, see the Commands documentation.
Solve common developer storage problems with practical step-by-step guides:
- Clean Xcode Cache and DerivedData from Terminal
- Clean Developer Caches on macOS
- Find and Remove Old node_modules on Mac
- Analyze Disk Usage on macOS from Terminal
- Clean AI Tool Artifacts on macOS
A typical cleanup takes three steps:
cleanmymac clean/purgeCleanMyMac CLI scans supported locations and groups what it finds.
Inspect categories and paths, then select or deselect what you want to remove.
After cleanup, CleanMyMac CLI shows what was removed and how much disk space was recovered.
Open the interactive interface or run exactly what you need. This makes CleanMyMac CLI useful both as an interactive cleanup tool and as part of command-line workflows.

cleanmymac cleanOr scan only one category:
cleanmymac clean junk
cleanmymac clean dev
cleanmymac clean trash[!TIP] Use
cleanfor shared caches and tool-generated junk. Usepurgefor removable dependencies and build artifacts stored inside your project folders.
Use purge to find generated files that accumulate inside development projects, such as node_modules, build directories, virtual environments, and compiled dependencies.
By default, it scans common project locations:
- `~/Projects`
- `~/Code`
- `~/dev`
- `~/GitHub`
- `~/Workspace`
Results are grouped by project so you can understand what each artifact belongs to before removing it:
$ cleanmymac purge

Artifacts older than seven days are preselected. More recent artifacts remain visible but unchecked, reducing the risk of removing files from active projects.
Scan the default project folders:
cleanmymac purgeOr provide a specific directory:
cleanmymac purge ~/Work/client-project[!NOTE]
purgeremoves generated artifacts, not project source code. Review every selected path before confirming, especially when scanning custom directories.
Use analyze when you want to understand where your storage has gone before deciding what to clean.
It opens an interactive explorer that sorts directories by size and lets you navigate deeper into the file system:

Removing an item requires an explicit selection and confirmation. Simply browsing through analyze does not modify your files.
Analyze your home directory:

cleanmymac analyze ~/Projects[!TIP] Start with
cleanmymac analyzewhen you know your disk is full but are not yet sure what is safe or useful to remove.
Use optimize for lightweight maintenance tasks that do not scan project files or developer caches.
Run all available optimization tasks:
cleanmymac optimizeOr run them separately:

CleanMyMac CLI was built around the workflows our own developers face every day. The CleanMyMac team uses it on our own Macs to clean development artifacts, inspect storage, and keep working environments under control.
🩷 We use the same commands we ship to you.
CleanMyMac CLI is in public beta and not yet feature-complete — expect commands and behavior to evolve.
We'd love to hear from you. For bugs and feature requests, open an issue on the issue tracker.

⭐ Star this repository to follow the Public Beta and help other developers discover the project.
CleanMyMac Desktop provides broader whole-Mac cleanup, application management, malware protection, and performance tools through a visual review interface. CleanMyMac CLI focuses on terminal-first developer cleanup and is not intended to replace the desktop app.
