electron-packager vs Tauri Bundler

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.

Tauri Bundler is free Rust tooling for packaging applications as operating-system bundles and installers. Its build command bundles an application for its configured formats by default, with separate build and bundle steps available when customization is needed. Distribution documentation covers Linux, macOS, Windows, Android, and iOS. Linux options include Debian, Snap, AppImage, Flatpak, RPM, and AUR; macOS apps can go through the App Store or be distributed as DMG installers. The guides also cover the Microsoft Store, Google Play, and the iOS App Store. Build instructions show commands for npm, yarn, pnpm, Deno, Bun, and Cargo, and Tauri documents a GitHub pipeline for building and releasing applications. Tauri describes the tooling as frontend-agnostic and says most frameworks work out of the box. However, it acts as a static web host and does not natively support server-based frontend alternatives such as SSR. Code signing is required on most platforms; macOS distribution outside the App Store also requires notarization. Tauri says major and minor releases undergo security audits. The bundler's public API is intended primarily for tauri-cli and does not strictly follow SemVer.
