Whippet

A macOS menu bar app that frees up disk space taken by iOS, Android, React Native and web development build artifacts and caches.

Requirements

• macOS 26 or later
• Xcode 26 or later
• Apple Intelligence enabled, for the on-device explanations (optional — Whippet falls back to built-in descriptions)

Build

git clone https://github.com/exploIF/whippet.git
cd whippet

Then build and install it into /Applications:

scripts/install.sh

The script builds a Release copy, quits Whippet if it's running, replaces /Applications/Whippet.app and launches it. Pass --no-open to skip launching. Run it again after pulling changes to update.

To work on the code instead, open the project in Xcode and press Run:

open Whippet.xcodeproj

scripts/install.sh also sets this project's Xcode build location to build/DerivedData.noindex (a per-user setting, only if you haven't chosen one). Spotlight skips .noindex folders, so only the copy in /Applications shows up in Spotlight and Launchpad.

Whippet has no Dock icon — look for the whippet in the menu bar.

The app is ad-hoc signed when built locally, so Gatekeeper won't block it on the machine that built it.

Tests

xcodebuild -scheme Whippet -derivedDataPath build/DerivedData.noindex/Whippet test
