electron-builder vs fpm

electron-builder is a free, open-source tool for packaging Electron apps for distribution on Linux, macOS, and Windows. It creates installers, portable builds, and archives, with targets ranging from DMG, PKG, AppImage, and DEB to NSIS, MSI, ZIP, and other formats. Command-line packaging and silent installation are supported. The electron-updater package provides differential updates, staged rollouts, and documented providers including GitHub Releases, Amazon S3, DigitalOcean Spaces, Cloudflare R2, Keygen, and generic HTTP(S) servers. Update manifests may be signed with Ed25519 and checked against a public key embedded in the app. Configured credentials enable macOS notarization and Windows Authenticode signing; ASAR integrity hashes are enabled by default, and Electron Fuses can disable selected features at package time. GitHub Actions guidance covers CI/CD builds and publishing. In v27, publishing must be explicitly requested. One build constraint matters: macOS signing requires macOS, and native dependencies generally need compilation on the target platform unless prebuilt binaries are used.

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.
