Diskscape

A map of what is actually filling your disk. macOS.

Point it at a folder and it draws every byte inside as a map. The biggest folder is the biggest box, so whatever is eating your disk is the first thing you see. No lists, no sorting, no digging three menus deep.

What it does

Reads about 200,000 files a second. A four-million-file home folder is mapped in roughly twenty seconds.
Folders take the colour of what is inside them — code, media, documents, archives, caches, git.
Worth a look: build output, node_modules, virtualenvs, Xcode DerivedData, iOS DeviceSupport, Gradle caches and fat git histories, found, grouped and totalled.
Move anything to the Trash without leaving the map.
Colour by age to find what you stopped using years ago, or count by number of files instead of bytes.

What it costs

Scanning and browsing are free, for good. The first seven days you use it, everything is unlocked. After that, Move to Trash needs a subscription.

Honest numbers

Diskscape counts what the disk actually gives up, not what the files claim. Hard links are counted once. Cloud folders live on someone else's server, so they are left out and labelled rather than inflating your total. Folders that will not answer are reported, never silently skipped.

Privacy

Diskscape reads only the folder you choose, and nothing about your files ever leaves your Mac. Full privacy policy.
