## What it is
A Node.js-based CLI tool that generates polished macOS DMG disk images for applications from a simple JSON specification. It supports custom backgrounds, icons, icon layouts, window sizing, various compression formats, and code signing.

## Use cases
- create a dmg installer for my mac app
- generate beautiful dmg images for osx application
- package electron app as dmg
- add background and icon layout to macos disk image
- code sign a dmg file
- build mac app installer from command line

## When to choose
- you need to distribute a macOS desktop app as a DMG with custom branding
- you want scriptable, repeatable DMG creation in a CI pipeline
- you need control over DMG window layout, compression format, or code signing

## When to avoid
- you target platforms other than macOS, since DMG creation requires macOS tooling
- you need a GUI-based DMG builder
- you need actively developed features, as the project is in maintenance mode
