How do I use Space Radar to analyze a remote server's disk space?

Export disk usage data from the server using `du -ak`, compress it if needed, and import the file into Space Radar. The app reads compressed .gz files directly, allowing visualization without remote access.

Space Radar vs WinDirStat: which is better for Windows?

Space Radar is cross-platform with faster scans and multiple chart types, while WinDirStat is Windows-only but more established. Choose Space Radar for multi-OS use or WinDirStat for a lightweight native Windows tool.

Can I run Space Radar on a headless Linux server?

No, Space Radar requires a desktop environment as it's a GUI application built with Electron, so it won't work on servers without a graphical interface.

How to pause or cancel a scan in Space Radar?

During scanning, use the pause/resume or cancel buttons in the interface—this feature was added in V6 to stop scans and view partial results interactively.

Is Space Radar free and open source?

Yes, Space Radar is MIT-licensed and free to use, with source code available on GitHub, but relies on community support rather than paid updates.

Does Space Radar work on Apple Silicon Macs?

Yes, V6 introduced native arm64 builds for M1/M2/M3 Macs, ensuring optimized performance on Apple Silicon without Rosetta emulation.

What is SpaceRadar?

Space Radar is a desktop application that visualizes disk space and memory usage using interactive charts like sunbursts, treemaps, and flamegraphs. It scans storage faster than traditional command-line tools and provides real-time previews, helping users identify large files and memory hogs. The app is cross-platform, supporting macOS, Windows, and Linux with native performance.

Target Audience

Developers, system administrators, and power users who need to analyze disk or memory usage visually and efficiently across different operating systems.

Value Proposition

It offers faster scanning than `du`, multiple visualization types, and cross-platform support in a single, free app. Unique features like remote server analysis, pause/cancel scanning, and Apple Silicon optimization make it a versatile alternative to built-in system tools.

Overview

Fast Disk And Memory Space Visualization App for Mac, Windows and Ubuntu

Use Cases

Best For

Identifying large files and folders consuming disk space quickly
Visualizing memory usage breakdown across processes
Analyzing disk contents from remote servers via exported data
Comparing storage usage across different directories with interactive charts
Monitoring system resources on macOS, Windows, or Linux with a unified tool
Exploring disk space with real-time scanning and navigation

Not Ideal For

Users needing command-line-only tools for scripting and automation
Headless server environments without desktop access
Projects requiring detailed historical data tracking or automated reporting
Systems with very limited RAM due to Electron's memory overhead

Pros & Cons

Pros

Fast Cross-Platform Scans

Scans disks faster than traditional `du` commands with real-time previews, as emphasized in the README's 'Fast Scanning' feature and V6 updates.

Multiple Visualization Types

Offers sunburst, treemap, and flamegraph charts for versatile analysis, allowing users to switch perspectives based on their needs.

Interactive Navigation

Includes drill-down with breadcrumbs, file opening in system managers, and pause/cancel scanning, making it highly user-friendly for exploration.

Remote Analysis Capability

Supports analyzing disk contents from remote servers by importing `du` output files, useful for server management without direct GUI access.

Cons

Electron Memory Overhead

Built on Electron, it can consume significant RAM compared to native tools, which might impact performance on memory-constrained systems.

Limited Network Drive Support

The README focuses on local disks and remote file imports, with no mention of direct network or cloud storage integration, limiting its use in networked environments.

Experimental Features Unstable

Features like 3D sunburst visualization are labeled experimental in V6 updates, potentially leading to bugs or incomplete functionality.
