Disk space, mapped

See what fills your Mac

Diskscape draws your disk as rings of folders, shows what grew since yesterday, and tells you when it will be full. It only reads, and never deletes a thing.

Coming soon to the Mac App Store Free, with Pro for $9.99 once

The Diskscape window: a ring map of a home folder, colored by content, beside the list of its folders with their sizes and shares.
Point at a folder to see inside: the pointer on Movies lights up its rings on the map and shows a card with 53.7 GB, 21.8% of the folder, video, and the change since yesterday.

The map

Each ring is a level deeper, each segment a folder at its share of the space, colored by what it holds. Point at one for its size, share, kind of content, path and change.

  • Click to go in
  • Used space no scan can see is a grey “?”
  • Sizes as Finder counts them on disk
See what grew since yesterday: the folder's change chart, 237 GB to 246 GB, over a map that marks what grew in red and what shrank in green.

Changes

Every scan keeps a small snapshot of your folders. Diskscape shows what grew or shrank, by how much, and follows the growth down to the folder it came from.

  • Since yesterday, free
  • A week, a month, a year or all time with Pro
Know when your disk will be full: two disks charted over 46 days, with one-off jumps marked and the date each would fill at this pace.

Forecast

A quiet daily snapshot charts how full each disk gets. Diskscape tells a one-off jump from steady growth, and says when the disk fills at this pace.

  • Free
  • In the background, at low priority
Keep an eye on space as you work: the menu bar item reads 27% · 295 GB ▲ 8.60 GB, and its panel lists the folders that grew most since yesterday.

Menu bar

Free space and the day's change sit next to the clock. Open the panel to see which folders grew most.

  • Choose what the item shows
  • The month's change with Pro
Get alerted when folders grow: an alert for .cache when it grows by more than 5 GB in a week; it has grown by 7.80 GB.

Alerts Folders · Pro

Set a limit, and macOS lets you know once it's passed. A disk more than 90% full is a free alert; for folders, Pro watches size, share of the disk and growth over a period.

  • Disk more than 90% full · Free
  • Folder larger than 50 GB · Pro
  • Grows by 5 GB in a week · Pro
AI ready: in Terminal, diskscape changes answers what took the space since yesterday — .cache +7.80 GB, Library +4.60 GB, Movies −3.80 GB — the same as the Diskscape window behind it.

AI ready

Diskscape has a command line made for coding agents such as Claude Code, Codex and Gemini CLI. They scan, compare with history, find what takes space, point at it on your map and set alerts — with the numbers you see in the window.

  • History a plain du can't see
  • Reads only; deleting stays your call
  • Diskscape → Connect an Agent…

And more

Small things, done carefully.

A snapshot a day

In the background, when the Mac is idle, so changes are ready whenever you look.

Favorites and search

Keep the folders you watch in the sidebar, and find any folder by name as you type.

Honest numbers

What couldn't be read is marked, not hidden, and Diskscape explains why its total differs from Finder's.

From Finder

Control-click a folder in Finder and choose Services → Preview in Diskscape for its map in a compact window.

Asks once

macOS asks you to confirm a disk or folder once; Diskscape remembers it until you tell it to forget.

Copy as Text

Paste a folder's sizes into a note, a ticket or a chat.

Pricing

Free, with Pro for the long view.

Free keeps your whole history from the first scan, so Pro opens all of it at once.
