About DiskMac

DiskMac is a Mac utility aimed at developers whose machines fill up with build artifacts. Finder shows big folders but not what is safe to remove, so DiskMac scans projects and tool caches and labels what each item is and how it comes back, covering Xcode build files and simulators, Docker images and build cache, and node_modules plus npm, pnpm and yarn caches.

Results can be explored in ten views, including a treemap, sunburst, flame graph, bubbles and a table, with Strata showing size and age together so forgotten projects stand out. The app only works inside the home folder and states that source code, .git folders, keys and passwords are never touched.

It runs on macOS 13 or later, scanning is free without an account, and the full app is a one-time purchase. It suits iOS, web and container developers who regularly run low on disk space.
