What diskbloom is
diskbloom is a free, open-source terminal disk visualizer for macOS and Linux. Its nested treemap recursively divides folders, with tile area showing allocated disk space. A bounded parallel scanner measures on-disk allocation and deduplicates hardlinks so shared data counts once. A second pane presents a tree with size bars, and a color legend identifies file extensions. Keyboard and mouse controls support selection, opening, and scrolling. Enter opens files in their default applications, while Space invokes Quick Look on macOS. Ctrl+X sends selected items to Trash by default; permanent deletion requires typing the action. Installation options include Homebrew, Go, and prebuilt binaries for macOS arm64 and amd64 and Linux amd64 and arm64. Building from source requires Go 1.26 or later. A truecolor terminal is recommended for the full palette. The project is a static binary with no dependencies and uses Apache-2.0 licensing.
