Leaves is a text-based disk usage treemap visualizer introduced on Show HN, designed for use on servers and containers where GUI tools are unavailable. It aims to improve disk space analysis in terminal environments.
A developer has introduced Leaves, a text-based disk usage treemap visualizer, on the Hacker News Show platform. This tool targets users managing remote servers or containers where graphical disk analyzers are unavailable, providing a visual way to understand disk space distribution directly in the terminal.
Leaves is a command-line utility that creates a treemap visualization of disk usage, similar to GUI tools like WinDirStat or DaisyDisk, but designed for environments where only text interfaces are available. It displays directory and file sizes in a hierarchical, visual format within the terminal, helping users identify large files and directories quickly.
The project was shared on Show HN by its creator, who highlighted its usefulness for server administrators and developers managing remote or containerized systems. The tool aims to fill a gap where traditional GUI disk analyzers cannot be used, offering a lightweight, accessible alternative.
According to the developer, Leaves is implemented in a way that emphasizes simplicity and clarity, making it easy to interpret even for users unfamiliar with treemap visualizations. The tool is open-source and available for download, with the developer inviting community feedback and contributions.
Enhanced Disk Management in Terminal Environments
This development matters because it offers a visual approach to disk space analysis within text-only environments, which are common in server and container management. By providing a treemap visualization in the terminal, Leaves can help users quickly identify large files and directories, improving maintenance efficiency and preventing disk space issues.
As GUI tools are often impractical or impossible to run on remote servers, this tool could become a valuable resource for system administrators, DevOps engineers, and developers who need a quick, visual insight into disk usage without leaving the command line.

Limitations of Existing Disk Usage Tools on Servers
Traditional disk analyzers like WinDirStat or DaisyDisk are graphical and require a desktop environment, making them unsuitable for remote servers or containerized systems. Command-line tools such as du provide raw data but lack visual representations, making it harder to interpret large disk usage patterns quickly.
The emergence of text-based visual tools like Leaves responds to this gap, offering a more intuitive way to understand disk space distribution within the constraints of terminal environments. Similar tools have existed in various forms, but Leaves emphasizes a treemap visualization, which is less common in text UI tools.
“Leaves provides a visual, hierarchical view of disk usage directly in the terminal, making it easier to identify large files and directories without GUI dependencies.”

Key Questions
How does Leaves compare to traditional disk analyzers?
Leaves offers a text-based treemap visualization within the terminal, unlike GUI tools like WinDirStat. It is designed for environments where GUIs are unavailable, providing a visual overview in text form.
Is Leaves suitable for large or deeply nested directories?
The developer claims it works well for typical use cases, but performance and clarity in very large or complex directory structures are still being tested.
Can Leaves be integrated with other system monitoring tools?
As an open-source project, it could potentially be extended or integrated, but current features focus on standalone disk usage visualization.
Is Leaves available for all operating systems?
The initial release is designed for Unix-like systems, including Linux and macOS, but cross-platform support depends on further development and community contributions.
Where can I find the source code or try Leaves?
The project is hosted on a public platform linked from the Show HN post, where users can download, review, and contribute to its development.
