About Storage Cleaner
Storage Cleaner is an independent Mac app. It's funded by one thing only: people who buy a license. There are no ads, no subscriptions and no data collection.
Why it exists
Developer Macs fill up in a way generic cleaners don't understand. Xcode keeps DerivedData, simulator runtimes and device symbols forever; every JavaScript project has its own node_modules; and local AI tools like Ollama and LM Studio download models of 5–40 GB each. macOS lumps it all into "System Data" and doesn't say what's safe to remove.
Disk visualisers show that a folder is big. General cleaners call it "junk". Storage Cleaner says what each item is, when you last used it, what happens if you remove it, and lets you undo, all on one screen.
How it's built
- Native and private. A Swift/SwiftUI Mac app. Scanning happens entirely on your Mac; there's no account and no analytics. See the privacy policy.
- Safe by default. Nothing is removed without your confirmation, files go to the Trash so you can undo, and every item is rated Safe, Review or Caution.
- Signed and notarized by Apple. Download it from this site or install it with Homebrew.
How we write and test the guides
The guides on this site explain how to clean each of these by hand, with or without the app. For every guide:
- Commands are run on a current Mac before publishing (macOS 26 and Xcode 26 as of September 2026), and each guide shows the date it was last checked.
- We say clearly what is safe to delete, what it costs to get back (a re-download or a slower first build), and what you should keep.
