LunarDisk is a macOS-only, open-source disk usage visualizer focused on helping users find and clean large storage consumers safely.
LunarDisk helps macOS users understand what is taking space on their machine and act on it safely.
- Built for: anyone running low on disk space, especially users who want a clear visual breakdown before deleting anything.
- How it works: choose a folder or volume, run a recursive scan, inspect the size breakdown, then drill into large directories and files.
- Open-source focus: readable Swift/SwiftUI architecture, modular scanning and visualization layers, and contributor-friendly scripts.
- Privacy model: local-first with least-privilege file access; no file-content collection or transmission.
- Latest release: GitHub Releases
- Prereq: Xcode command-line tools + XcodeGen (
brew install xcodegen). - Generate project:
./scripts/gen.sh - Build:
./scripts/build.sh - Test:
