DevCleaner

Reclaim the disk space your development tools left behind — and know what you are deleting before you delete it.

Download for macOS

DevCleaner deletes files. It always scans first and shows you what it found; nothing is removed until you choose it. Items that cannot be recovered are marked as such and ask for a second confirmation.

It works entirely on your Mac. There is no account, no network code in the app, and nothing it finds is sent anywhere.

What it is

A developer's Mac fills up in places Finder never shows you: package-manager caches, SDK downloads, simulator runtimes, build artefacts, virtual-machine images, model weights. DevCleaner knows where those live for the tools you actually have installed, scans them, and lays out what it found with a size against each one.

The point is not just the number. Every item says why it is safe to remove and what happens afterwards — whether the tool rebuilds it on its own, downloads it again when needed, or cannot get it back — so you can clear what costs you nothing and leave what would cost you an afternoon.

Features

Knows the tools

Homebrew, npm, pip, Docker, Xcode, CocoaPods, Gradle, fvm, Android SDK and emulators, iOS simulators, JetBrains, Hugging Face, pub, bun, uv, Go — and VM images from UTM, Parallels, and Docker.

Explains every item

A plain-language reason it can go, and a badge for what comes next: rebuilt automatically, downloaded again, or not recoverable.

Preview before delete

Scan first, always. You pick what goes. Irreversible items get an extra confirmation step.

Local and free

No account, no telemetry, no network code. Signed with a Developer ID and notarized by Apple.

Screenshots

Xcode card expanded: each item explains why it is safe to remove, with a badge for what happens afterwards

Download DMG

Install

Open the downloaded DMG.
Drag DevCleaner to your Applications folder.
Launch it. It is notarized, so it opens without a Gatekeeper warning.

When a scan first reaches your Desktop, Documents, Downloads, or an external volume, macOS asks whether to allow it. Say no and DevCleaner simply skips that location.
