The DaisyDisk experience, rebuilt in SwiftUI and open-sourced — every byte of your Mac, finally visible.
The iconic radial chart of disk usage — folders sized proportionally, the offenders impossible to miss.
Drag files into a basket as you browse. Review, then delete the whole basket at once.
Hit Spacebar on any file to preview it inline — never delete the wrong thing again.
Surfaces system-hidden purgeable storage so you finally see where your disk really went.
The PocoDisk icon is generated at build time entirely in Swift — no PNG assets to maintain.
