electron-packager vs IzPack

electron-packager bundles Electron app source code with a renamed Electron executable and supporting files into folders ready for distribution. It works as a command-line tool or a Node.js library called through JavaScript. Packager can find or download a matching Electron release and build for a selected platform and architecture, all valid combinations, or the host combination. Output targets include Windows, macOS—including Mac App Store targets—and Linux; these are also the listed host platforms. Documented target architectures include x86, x86_64, arm64, universal macOS, Linux armv7l, and Linux mips64el, though some depend on Electron versions. CLI options include a regular-expression ignore filter for files and folders. Electron Forge uses Packager internally, and installer tools can use its output folders to create distributables. The free, open-source Node.js tool requires Node.js 22.12.0 or higher, and local installation is recommended. Signing a macOS or Mac App Store bundle requires building on a macOS host. The project also notes that even a minimal zipped app is approximately the size of the matching zipped Electron binary.

IzPack generates installers for packaging, distributing and deploying Java applications. It creates one installer that runs on operating systems with a Java virtual machine, with Windows, Linux, Solaris and Mac OS X listed as destinations. Users can select installer components and appearance, then extend installers with additional features. Optional native integration can create desktop shortcuts, modify a system registry or switch to an administrator account. Documented capabilities include command-line packaging, silent installation, auto-update support and CI/CD integration. Output includes standard JAR installers, web installers and pack JARs. The download page identifies IzPack 5.2.7 as the current release. A Maven plugin is documented, with links to independent Gradle, Scala SBT and Apache Buildr plugins. IzPack is published under the Apache Software License 2.0. The project uses mailing lists for updates and feedback and accepts GitHub pull requests. The Windows native launcher from IzPack 4 is not supported in version 5 because it lacks a maintainer.
