TL;DR
A developer posted Leaves, a text-based treemap visualizer for disk usage, on Show HN. It offers a GUI alternative for analyzing disk space on remote servers and containers, where traditional GUI tools are limited.
A developer has introduced Leaves, a text-based disk usage treemap visualizer, on Show HN, aiming to provide an alternative to GUI disk analyzers for remote servers and containers where graphical tools are limited or unavailable.
Leaves is designed as a command-line utility that visualizes disk space usage through treemaps in a text user interface (TUI). Unlike traditional GUI tools such as WinDirStat or DaisyDisk, Leaves operates entirely within terminal environments, making it suitable for servers, containers, or remote systems accessed via SSH.
The project was shared on Show HN by its creator, who highlighted the challenge of analyzing disk space on systems without graphical interfaces. Existing solutions like ‘du’ are functional but lack visual clarity, especially when dealing with large directories. Leaves aims to fill this gap by providing a clear, hierarchical, and visual representation of disk usage in a text format.
While the tool is still in development, the initial release includes core features such as directory traversal, treemap visualization, and interactive navigation within the terminal. The developer has shared the source code openly, inviting community feedback and contributions.
Implications for Disk Management on Remote Systems
Leaves addresses a significant gap in disk analysis tools for environments where GUIs are impractical or unavailable. By enabling visual disk space analysis directly within terminal sessions, it can help system administrators and developers quickly identify large files and directories, improving maintenance efficiency.
This development is particularly relevant for managing cloud instances, Docker containers, and remote servers, where traditional GUI tools cannot be easily deployed. It supports a more intuitive understanding of disk usage, potentially reducing downtime and optimizing storage management.

Limitations of Existing Disk Usage Tools in Headless Environments
Most existing disk analysis tools are GUI-based, such as WinDirStat, DaisyDisk, or Disk Inventory X, which require graphical interfaces to operate. On remote servers, especially those accessed via SSH, users rely on command-line utilities like ‘du’, ‘df’, or ‘ncdu’.
‘du’ provides raw data but lacks visual clarity, making it difficult to interpret large directory structures quickly. ‘ncdu’ offers a text-based interface but does not include visual treemaps, which can be more intuitive for understanding space distribution.
Leaves builds upon these limitations by combining the hierarchical view of ‘du’ with a treemap visualization in a text UI, offering a more accessible and visual approach without requiring a GUI environment.
“Leaves aims to bring visual clarity to disk usage analysis directly within terminal environments, making it easier to identify large directories without a GUI.”

Features and Maturity of Leaves Remain Uncertain
As Leaves is in early development, it is not yet clear how fully featured or stable the tool will become. Details about its performance, scalability, and user interface refinements are still emerging.
Community feedback and contributions could influence future development, but the current version may lack some advanced features found in mature GUI tools.

Key Questions
What platforms does Leaves support?
Leaves is designed to run on Unix-like systems that support terminal-based applications, including Linux and macOS.
How does Leaves compare to existing tools like ‘ncdu’?
While ‘ncdu’ provides a text-based interface for disk usage, Leaves adds a visual treemap component within the terminal, aiming to improve interpretability of storage distribution.
Is Leaves suitable for large directory trees?
Early versions may face performance challenges with very large directories, but improvements are planned to enhance scalability.
Can Leaves be integrated into automated scripts?
Yes, as a command-line utility, it can be scripted and integrated into system monitoring workflows.
Where can I access the source code?
The project is open source; the repository is linked in the original Show HN post for community review and contributions.
