Move Xcode to Your
External SSD.

Simulator Runtimes eat 40–80 GB of your Mac. DiskPort moves them to your external SSD via symlinks — Xcode never notices the difference.

Where did
100 GB go?

Every Xcode developer knows the dread. "Your disk is almost full." You check, and somehow ~/Library/Developer/ is eating over 100 GB.

DerivedData from forgotten projects. Device support for iOS versions you no longer test. Simulators you didn't know existed.

  • DerivedData grows silently with every build
  • Old device support files linger for years
  • Deleting the wrong thing breaks your build
  • rm -rf is a gamble, not a strategy
Features

Move it. Don't delete it.

The only tool that relocates Xcode assets to external storage — no other app does this.

Core Feature

Simulator → External SSD

Move iOS/watchOS Simulator Runtimes (8–18 GB each), DerivedData, Archives, and Device Support to your external SSD. DiskPort creates symlinks — Xcode sees no change.

One-click migrate. One-click rollback. Manifest-tracked. Zero breakage.

Free

The Storage Map

A treemap visualization that shows your entire Xcode footprint in one glance. See exactly which simulators, projects, and caches are burning space.

Color-coded by age. Click any segment to act.

Pro

Quiet Monitor

A discreet menu bar indicator that reflects your storage health. Get notified when DerivedData crosses your threshold — before your disk fills up.

Set auto-clean rules. Forget about it.

Pro

Project Awareness

Stop seeing cryptic DerivedData hashes. DiskPort resolves them to your actual project names, so you know exactly which project is burning 8 GB.

Sort by size, last built, or name.

Pricing

One price. Yours forever.

No subscription. No recurring fees. A tool that respects your wallet like it respects your disk.

From developers

Built for people like you.

"I had no idea DerivedData was eating 62 GB until DiskPort showed me the treemap. Cleaned up in two clicks."
Marco K.
iOS Developer
"The relocate feature is genius. Moved 80 GB of archives to my external SSD and Xcode doesn't even know."
Sarah L.
macOS Engineer
"Finally, a tool that shows which project each DerivedData folder belongs to. Should've been built into Xcode."
James T.
Indie Developer

Free your Mac. Keep your simulators.

Move 60+ GB of Xcode simulators to your external SSD in one click. Xcode won't even notice.
