GPLv3 read-only disk space visualizer for macOS 14+ and Linux, from Northwestern computer-engineering student Lucas Takayasu: cushion and flat treemaps plus a sunburst over one Swift 6 core (NeodiskKit, derived from Radix's MIT scan engine; sunburst ported from it). macOS SwiftUI/AppKit, Linux GTK 4/libadwaita shipped October 2026, Windows Win32/Direct2D in progress. Cleanup is review-then-Trash only: refuses system folders and the home folder, re-verifies each item is unchanged since the scan before moving. Content-hash duplicate finder, between-scan changes view, snapshots, 8-language UI, Sparkle updates. Developer ID-signed/notarized dmg via GitHub and official homebrew-cask; Linux AppImages and tarball. 628 stars.

Launch post: 'huge shoutout to Colin for Radix! A huge inspiration for this project and where most of the scanning backend code was forked from.' Readme: NeodiskKit is derived from Radix's MIT scan engine and the sunburst is ported from it.
Launch post: 'I made a modern version inspired by my experience with Disk Inventory X ... It also has a sunburst view inspired by SquirrelDisk.' Readme credits DaisyDisk too; no code taken from DIX, GrandPerspective, or DaisyDisk.

I always loved to use visualizers to help me delete bigger files and clean out my disk, but I always felt a little scared of deleting stuff through these programs. — Problem statement
So I made it read-only, in a way that you can only delete your files through Finder. — Trust signal
So I made a modern version inspired by my experience with Disk Inventory X! It's called Neodisk It's native to Apple Silicon, made with Swift — Virtue
