What developer folders usually take the most space on Mac?

Common large developer folders include node_modules, Xcode DerivedData, simulator data, Pods, Gradle caches, Rust target folders, SwiftPM .build folders, Docker data, and Homebrew caches.

What is the safest cleanup workflow?

Scan only folders you choose, review the results, unselect anything important, move selected folders to Trash, and empty Trash only after confirming nothing important was removed.

Mac developer cleanup

Mac developer disk cleanup guide.

Developer tools create large generated folders. DevClean focuses on making those folders visible and reviewable instead of running broad system cleanup.

Common folders to review

node_modules for JavaScript projects
Xcode DerivedData, simulator caches, DeviceSupport, and archives
Pods and CocoaPods cache for iOS projects
Gradle, npm, pnpm, Yarn, Python, SwiftPM, and Rust build caches
Docker build cache, Docker Desktop data, Colima data, and Homebrew cache

Safe cleanup workflow

Start with a specific project or developer folder, review every result, keep anything you are unsure about, and move selected folders to Trash. Permanent deletion should stay rare.

Why not use a general cleaner?

Developer folders have context. A generic cleaner may not explain what generated a folder or how it can be recreated. DevClean labels the folder type, risk, path, and cleanup method before anything changes.
