Leaves
Leaves is an open-source, Rust-built command-line tool that turns disk usage into a text-mode treemap, drawing nested rectangles sized by file and directory weight directly inside a terminal, including over SSH on headless servers where GUI analyzers can't run.
Developer patonw shipped Leaves' first release, v0.1.0, on July 6, 2026, inspired by classic GUI tools WinDirStat and QDirStat and built to handle millions of files via Rust's multi-threading. A July 16 Show HN post pushed it to 85 points and 25 comments, with reviewers comparing it directly to ncdu, WizTree, and GrandPerspective.
Think of it as WinDirStat's colored rectangles redrawn with keyboard-driven terminal blocks instead of a GUI window.

Outlook
6-month signal projection and commercial timeline.
Rust performance and a strong Show HN debut win developer goodwill, but terminal disk-usage tools are a mature, crowded niche.
Risk · ncdu, dua-cli, gdu, and dust already own this category, limiting how much of the market a newcomer can take.

Ideas for term “Leaves”
Buildable pitches — turn this term into an article, site, product, post, newsletter, video, or course. Steal any card and run with it.
No current roundup covers Leaves; most disk-analyzer comparisons still favor GUI-only tools like WinDirStat.
Sysadmins searching for headless-server disk tools get list-only ncdu results; a visual SSH workflow guide is underserved.
HN commenters explicitly asked for brew install; no official package exists yet, leaving room for a third-party maintainer.
The creator confirmed this is unbuilt but wanted; a fork or plugin that ships it first captures early mindshare.
First-person migration story capitalizing on the 72-hour attention window right after the Show HN launch.
Visual-first comparison suits YouTube; the tool's colored-rectangle output is inherently screenshot-friendly.
One Rust developer needed ten days and four releases to prove you don't need Electron to visualize a hard drive — you need a grid of colored block characters.
A full disk on a headless server used to mean squinting at `du -sh */` output — now it means a proportional rectangle map rendered in the same terminal window.
