Mac

Discover what's eating your disk space. Visual analysis, smart cleanup recommendations, and one-click removal. Privacy-focused and developer-friendly. WhatsBig helps you discover what's taking up space on your Mac and clean it up with confidence. VISUAL DISK ANALYSIS See exactly where your storage is going with an interactive donut chart. Click any segment to instantly view details and cleanup options. Real-time size display shows exact bytes and percentages as you explore your files. SMART CLEANUP RECOMMENDATIONS WhatsBig intelligently identifies files that are safe to remove: • Regenerable Files - Caches, node_modules, and Xcode DerivedData that apps recreate automatically • System Generated - Logs and temporary files created by the system • Installers - DMG and PKG files that are typically not needed after installation • Large Archives - ZIP files worth reviewing to see if contents were extracted Every recommendation includes clear reasoning so you can decide with confidence. One-click cleanup moves files to Trash safely. HIERARCHICAL FILE BROWSER Navigate your files with a size-sorted folder tree. Largest folders appear first so you find space hogs fast. Folders are grouped by impact: Large (100MB+), Medium (10-100MB), and Small. Visual capacity bars show how much each folder contributes to its parent. HIDDEN FILE DISCOVERY Toggle hidden files to reveal dotfiles and system folders. See exactly how much space is hiding in invisible files. Category badges identify hidden, cache, system, and package files at a glance. DEVELOPER FRIENDLY Perfect for developers who accumulate build artifacts: • node_modules directories from npm/yarn • CocoaPods folders • Swift Package Manager .build directories • Xcode DerivedData per project Quick scan shortcuts let you jump directly to Downloads, Caches, or Xcode DerivedData. PRIVACY FIRST • No network access - your files never leave your Mac • User-selected access only - scans only folders you explicitly choose • No telemetry - zero tracking, zero analytics • Sandboxed - respects macOS security best practices Built natively with SwiftUI for a fast, responsive experience that feels right at home on your Mac. Supports both light and dark modes. Know what's big. Clean with confidence.
