🫧 TidyDisk

Free disk cleaner for Mac developers. Reclaims the gigabytes hiding in Xcode DerivedData, node_modules, simulators, package-manager caches and forgotten projects — safely, with everything reviewed before it's touched.

Website & download: tidydisk.riekapps.com

• 100% on-device — nothing leaves your Mac, no account, no telemetry
• Native SwiftUI, universal binary (Apple Silicon + Intel), a few MB on disk
• Notarized by Apple

Install

Homebrew:

brew install --cask prateekcode/tap/tidydisk

Or manually: download the zip from tidydisk.riekapps.com, unzip, drag TidyDisk.app to Applications.

Requires macOS 14 (Sonoma) or later.

What it cleans

TidyDisk probes your Mac at launch and only shows what's actually there:

• Smart Scan — Xcode DerivedData & caches, CocoaPods, npm/pnpm/yarn, Gradle, Homebrew, SwiftPM, Docker, simulator runtimes, old device-support folders, app caches, Trash, and more
• Space Lens → Projects — finds every dev project on your Mac (via .git, package.json, pubspec.yaml, *.xcodeproj, …) and cleans their build artifacts (node_modules, build, .dart_tool, Pods, .gradle); can also push a project to a private GitHub repo or archive it to iCloud before you delete it
• Large Files — everything over 200 MB in your home folder
• Duplicates — identical files in Downloads & Desktop, newest copy kept
• Menu bar — free space at a glance, one-click scan, optional weekly scan with a notification

Three risk tiers keep it safe: safe caches are pre-selected, aggressive and nuclear (e.g. all node_modules) always need an explicit opt-in. File deletions go to Trash where possible.

Build from source

Pure SwiftPM — no Xcode project needed:

./build.sh            # build + ad-hoc sign TidyDisk.app
./build.sh --install  # also copy to /Applications

The task catalog lives in Sources/TidyDisk/Models/Catalog.swift — add a CleanupTask there to extend the app.

Notes

• Emptying Trash and reading some app containers needs Full Disk Access (System Settings → Privacy & Security). Without it those items report 0 and are skipped.
• The weekly scan is a LaunchAgent running TidyDisk --scan-notify headless; its plist points at the app's executable, so re-toggle it if you move the app.
