SpaceBrowser

Cross-platform disk space visualizer

SpaceBrowser scans a folder or volume and displays its contents as a size-proportional treemap, making large files and directories easy to identify.

The project is open source and inspired by SpaceMonger 1.4.

Features

• Interactive treemap
• Navigation
• Optional free-space display
• Scan progress and cancellation
• Settings dialog
• Context actions
• Windows, Linux and macOS (not tested)

Usage

Prebuilt versions for Windows, macOS, and Linux are available on the Releases page. Download the file for your platform and run it directly.

To build SpaceBrowser from source, install Go 1.25 and the Wails v2 development dependencies, then run:

git clone https://github.com/Kiord/SpaceBrowser.git
cd SpaceBrowser
go install github.com/wailsapp/wails/v2/cmd/wails@latest
wails build

The resulting application is placed in build/bin. For development with automatic reloads, use:
