SpaceBrowser

October 2025

SpaceBrowser is a cross-platform file system viewer that allows you to monitor disk usage at a glance. Github

A Go backend parses the file system, computes a treemap and sends that to a webview (Wails) for display.

SpaceBrowser is an independent open-source project inspired by SpaceMonger 1.4.
