Disktree, Tobi Lütke’s disk treemap, replaces Disk Usage as a default app in Omarchy 4.5
The terminal-based dua is out. Omarchy 4.5 ships a graphical treemap from Shopify’s Tobias Lütke that calls out the regenerable caches worth a look and lets you mark files and folders, then remove them.

Running out of space on Omarchy is about to look a lot more colorful. Disktree, a disk treemap written by Shopify’s Tobias Lütke, replaces the old Disk Usage TUI as a default app in Omarchy 4.5, and it’s in the third release candidate published on November 2, 2026. The pull request behind it, “Replace Disk Usage TUI with Disktree”, was opened and merged by DHH into the quattro branch on October 7, 2026, and the app has been in the 4.5 release candidates since RC1. For everyone on the stable channel, it’s coming in the next version.
The RC3 notes describe it as “a treemap of what fills a disk, colored by kind, with the regenerable caches worth a look called out, so you can mark what should go and remove it.” It sits in the Deprecations section of the notes as “Replace the Disk Usage TUI with Disktree”, and the opening summary lists it among the four new default apps alongside Hype, Monologue and Signed.
The change itself is small. According to the PR, disktree-bin takes the place of dua in Omarchy’s default package set, and Omarchy uses Disktree’s own desktop entry so it shows up in the launcher under its own name, scanning your home directory by default. On existing machines, a migration installs Disktree, removes dua and deletes the old per-user “Disk Usage” launcher. The manual entry moves from the TUIs section to the GUIs section, with disktree --disk documented for whole-disk scans.
Disktree lives at tobi/disktree, an MIT-licensed project built in Rust with GPUI. The repository was created on September 24, 2026, its latest release is v0.11.0 from October 4, 2026, and it had 3,926 stars and 252 forks when we checked. Its tagline reads: “A treemap for finding and removing what fills your disk, for Omarchy.” The README says it follows your Omarchy theme and behaves like the rest of the desktop.
The README goes into detail on how it works. Every directory becomes a nested mosaic sized by its real disk cost, and the color shows what kind of data it is: code, agent scratch, toolchains, synced files, git, media, documents and caches. A diagonal hatch marks space you can get back, such as caches, package stores and build output. The side panel has a “Worth a look” list of the largest things that could plausibly go, and for a git checkout it shows uncommitted changes, stashes and unpushed commits.
Removing files is deliberately careful. You mark tiles with Space, press c to review the list, then move it all to the trash or delete it permanently, and permanent deletion always asks first. According to the README, the filesystem root, the scanned root, your home directory, mount points and system trees like /usr and /etc are refused. You can also hand the list off instead: a copies a prompt for a coding agent to do the cleanup, and s saves the list as a text file.
There’s more than the default home scan. You can press g or run disktree --disk to widen it to the whole disk, and the README says the wider scan reuses what has already been measured. disktree ssh <host> scans a server read-only and exports a delete script rather than removing anything remotely. Want to try it before 4.5 lands? The README points Omarchy users to the AUR with yay -S disktree-bin.
