Show HN: Leaves – A text-UI disk usage treemap visualizer
GUI disk analyzers are great for figuring out what's filling up your laptop/desktop drive.
On containers or remote servers, the options are limited to purely text based
utilities (e.g. du) or list-centric TUIs (e.g. ncdu) which are usually limited
to viewing one directory at a time.
I created leaves to fill that gap.
Inspired by classic utilities like WinDirStat and KDirStat, it uses a
2-dimensional treemap^1 visualization to show the entire directory hierarchy
with proportionally sized rectangles.
It's performant enough to handle millions of files, thanks to Rust and
multi-threading. However, block characters aren't as suited as pixels for
resolving a large number of items. Leaves can show file-type summaries per
directory or partition the top-level directories by extension, allowing you to
see not only where space is being used, but als

o how.
For instance, I can see the largest chunk of my home directory is taken up by
uv caches for python and old Linux ISOs that I could easily re-download if
needed. Or in a particular container, +600MB is used by standard Rust
documentation and tutorials, and that it is the only location with HTML/JS files,
when only the libraries and build tools are needed (note to self: remember to
use the minimal profile next time).
