electron-packager vs NSIS

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.

NSIS is a free programmer’s tool for creating self-contained Windows executable installers and uninstallers. Its scripting language handles variables, functions, string manipulation, and custom installation logic, including installing or removing software, changing system settings, and extracting files. Developers can choose classic or modern wizard interfaces, create custom pages, and provide multiple interface languages, including right-to-left languages. Compression options include ZLib, BZip2, and LZMA. Plug-ins can extend installer tasks and interfaces, download files, make internet connections, or patch existing files. The compiler preprocessor can combine projects, automate builds, and produce lite or full variants. Installers can support command-line packaging, silent installation, and CRC32 self-checking. The compiler can be built on POSIX systems such as Linux and BSD, but generated installers run on Windows. Documentation links to a FAQ, wiki, and forum.
