Disk cleaners
Open-source disk cleaners for Mac that find caches, logs, build folders and other removable files, then let you review them before deleting.
Over time a Mac collects caches, logs, old downloads, developer build folders and other files that can be regenerated or are no longer needed. A disk cleaner scans for these, groups them by size and source, and lets you remove what you choose to free up space.
Deleting the wrong files can break apps or lose data, so review every result before removing it. Prefer tools that explain what each item is, send selections to the Trash first, and let you limit scans to the areas you understand, such as Xcode or package-manager caches.
