electron-builder vs IzPack

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.

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.
