DerivedData never stops growing.
Every branch, scheme and Xcode version leaves another build folder behind.
Made for Xcode, package managers and local models.
Keep the project.
Keep the project.
Lose the build-up.
Build output, package caches, simulators and local models can quietly take more space than your code ever will. spacerecover finds them, says what rebuilds, and never touches your projects.

SOUND FAMILIAR?
Where the space goes.
Simulators multiply.
Each new iOS runtime and device you test on keeps its own copy of apps and data.
Caches live everywhere.
npm, Gradle, CocoaPods, pip, uv, Swift packages, Homebrew and model downloads all keep their own stores.
HOW SPACERECOVER HELPS
Made for how
you actually work.
Every finding says what it is, why it’s there, and what happens if it goes. You decide.
Clear what rebuilds. Keep what ships.
Xcode DerivedData is cleared with one choice. Archives are listed separately for review, because you may need them to symbolicate crashes or ship again.
- Quit Xcode first, rebuild later
- Archives always reviewed
- No arbitrary shell commands
Every package manager, one view.
Homebrew downloads, npm, Gradle, CocoaPods, pip, uv, Swift Package Manager and Dart/Flutter caches, each with what happens next time you build.
- Tool-specific explanations
- Stop builds before cleaning
- Projects in your code folders protected
See what your local AI is storing.
Ollama and Hugging Face model downloads are listed per model. Docker storage is shown with guidance to use Docker’s own controls, so volumes stay safe.
- Model-by-model review
- Persistent volumes protected
- Simulators managed through Xcode
CLEAR AT EVERY STEP
From “what’s taking space?”
to “that feels better.”
Scan for free.
Findings appear as the scan runs. Stop any time; nothing changes while spacerecover looks.
See what you’d get back.
One number up front: the space that’s safe to clear now. Everything else is grouped, sized and explained.
Clean, and check the result.
spacerecover measures free space afterwards, shows what’s waiting in the Trash, and lets you put anything back.

How to clear Xcode DerivedData, archives and simulators
Xcode can use tens of gigabytes. Here is how to safely delete DerivedData, old archives, device support files and unused simulators and runtimes on your Mac.
Read the guideHow to clear Homebrew, npm, pip, Gradle, CocoaPods and Docker caches on a Mac
Package managers and dev tools keep large caches. Here are the official commands to clean Homebrew, npm, Yarn, pnpm, pip, uv, Gradle, CocoaPods, Dart, Cargo and Docker safely.
Read the guideWhat is System Data on a Mac, and how do you reduce it?
System Data in Mac storage can grow to tens of gigabytes. Here is what it contains, why it changes, and the safe ways to reduce it without deleting files macOS needs.
Read the guideGOOD QUESTIONS
Know before you make room.
Will it delete my source code or Git repositories?
No. Project folders are scanned so you can see their size, but source code is never selected for cleanup. Untracked files are not treated as disposable.
Is deleting DerivedData safe?
Yes, Xcode recreates it. Your next build will take longer while it rebuilds and re-indexes. Quit Xcode before clearing it.
Does it run docker system prune or similar commands?
No. spacerecover does not run blanket prune commands. Docker storage is shown for review with guidance to use Docker Desktop’s own storage controls.
