Treemap view of a full disk in Dev Box Cleaner

Your whole disk, one picture

Cleanup basket reclaiming 82 GB in Dev Box Cleaner

Clean up with confidence

Queue folders into the cleanup basket and watch the reclaimable total add up. One click moves everything to the Trash — reversible, safe, and gone are the 82 GB you didn't need.

Built by developers, for developers

Dev machines collect junk like no other Mac. We know, because ours do too — so the usual suspects get first-class treatment.

Smart Cleanup grouping node_modules, package manager caches and Xcode leftovers

Xcode DerivedData & friends

Smart Cleanup hunts down the classics automatically: DerivedData, old Archives, iOS DeviceSupport, simulator caches, stray node_modules folders and every package manager cache on the disk — each grouped with a running total, all safe to remove and easy to rebuild.

The menu bar widget keeps live sizes for these hotspots, so you can clear DerivedData between builds without even opening the app.

Questions & answers

How does the free trial work?

Download the app and use everything free for 7 days — no account, no card. When the trial ends you can still scan and explore; cleaning requires a license.

How do I activate my license?

After purchase, your license key arrives by email within a minute. Open the app, click “License”, paste the key — done. One key works on up to 2 Macs.

Is it safe? Can it break my Mac?

The app is sandboxed and notarized by Apple. It never touches anything you didn't explicitly select, items are moved to the Trash (undoable), and files owned by the system are excluded from deletion entirely.

I'm moving to a new Mac — what do I do?

In the app's License screen click “Deactivate this Mac” to free up a seat, then activate on the new machine with the same key.

I lost my license key.
