OmniDiskSweeper
Find large files on a Mac and inspect what is taking up space
Find and clean stale developer caches on your Mac

Sluice is a Mac menu bar utility for finding disk space consumed by development tools. It inspects categories such as Xcode build data, simulator files, Docker caches, Gradle data, and package-manager caches, then shows what could be removed and why. Its cleanup logic watches for active builds and pauses when development work needs those resources.
The free version includes a disk-space gauge, category scanning, manual cleanup, low-space warnings, and command-line status checks. Developers can use it to investigate a nearly full machine or check available space before starting a release build. It supports Apple silicon and Intel Macs running macOS 14 or later. Scheduled cleanup, custom folder rules, and other Pro features are announced as coming soon.
