electron-packager vs fpm

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.

fpm is a free, open-source command-line tool for creating packages for existing package systems. It accepts sources such as local directories, npm packages, CPAN modules, Python packages, Ruby gems, and existing RPM or Debian packages. Outputs include Debian, RPM, FreeBSD, macOS, Arch Linux, Alpine, Solaris, Snap, tar, zip, shell archive, and other listed formats. fpm can convert an RPM package to Debian, remove files, change metadata or dependencies, and strip pre, post, or maintainer scripts. It is written in Ruby and installed with `gem install fpm`; Ruby must be installed first, and some formats need additional system tools. Docker is documented as a way to run fpm without installing those tools locally. Building an osxpkg package requires macOS. The tool supports Linux, macOS, and self-hosted use. Documentation is described as a work in progress and not extensive. The listed release is version 1.18.0, released August 26, 2026. The license is identified as MIT-like.
