electron-builder

electron-builder is a command-line tool for packaging Electron apps into desktop releases. It is best suited to developers shipping across macOS, Windows and Linux who want packaging and update workflows together. Its flexibility is valuable, but signing and native dependencies make platform-aware build planning essential.

Overview

electron-builder turns an Electron app into installers, portable builds and distribution-ready archives. The range of formats helps teams support different operating systems and installation preferences from one packaging workflow. Command-line packaging and GitHub Actions guidance suit automated release pipelines; teams that need a visual installer-authoring environment should look elsewhere.

Packaging can be paired with update delivery through the separate electron-updater package. In v27, publishing must be explicitly requested with a CLI flag or configuration option, which helps avoid releasing artifacts as an unintended side effect of a build.

Key features

Broad packaging targets

Outputs span macOS DMG, PKG and MAS; Linux AppImage, Snap, DEB and RPM; and Windows NSIS, MSI, AppX and MSIX. Portable EXE builds and archive formats including ZIP, 7z and tar variants give teams alternatives to conventional installers. Silent installation is supported for unattended deployment. This breadth is useful for projects distributing through several channels, though each target adds choices to manage in the release process.

Updates and release security

electron-updater supports differential updates, staged rollouts and multiple providers, including GitHub Releases, Amazon S3, DigitalOcean Spaces, Cloudflare R2, Keygen and generic HTTP(S) servers. Differential delivery can reduce the amount users need to download; staged rollouts let teams distribute updates progressively. Update manifests can optionally be signed with Ed25519 and checked against a public key embedded in the app before downloads, adding an integrity check to update delivery.

Signing and package integrity

With credentials configured, electron-builder supports macOS notarization and Windows Authenticode signing. ASAR integrity hashes are enabled by default, and Electron Fuses can disable selected Electron features at package time. These safeguards make it a credible choice for teams treating distribution security as part of release engineering, but they do not remove the need to configure credentials and build on the right platform.

Build pipeline and Forge

GitHub Actions CI/CD guidance covers building and publishing Electron apps. Electron Forge maker packages can create electron-builder targets, but publishing, auto-update and code signing require electron-builder to be the primary build tool. Forge users should account for that boundary before adopting it as a packaging-only step.

Pricing

electron-builder is open source and free. The electron-builder plan costs nothing. There are no paid tiers to weigh against usage caps or seat limits, making it a straightforward option for teams that want a capable packaging workflow without a software subscription.

Platforms

It targets macOS, Windows and Linux, but building for those platforms is not entirely interchangeable. macOS code signing works only on macOS, and native dependencies generally need to be compiled on their target platform unless prebuilt binaries are used. Teams building on CI should plan platform-specific runners or suitable prebuilt dependencies rather than assume one environment can produce every signed release.

Who it's for

electron-builder is a strong fit for Electron developers and teams that need multiple desktop package formats, automated builds and configurable update delivery. It is especially useful when one release pipeline must serve several desktop platforms. It is less suitable for teams that expect signing and native compilation to be platform-agnostic, or that prefer a graphical installer design tool. Community and package resources are available through GitHub Issues and npm.

Pros and cons

• Pro: Extensive formats across macOS, Windows and Linux let a project serve different distribution channels without relying on a single installer type.
• Pro: Differential updates, staged rollouts and several provider options give teams flexibility in how they deliver releases.
• Pro: Default ASAR integrity hashes, optional signed update manifests, and signing support address different parts of package and update security.
• Con: macOS signing requires macOS, while native dependencies generally need target-platform compilation; cross-platform release infrastructure needs planning.
• Con: Forge integration does not cover publishing, auto-updates or code signing unless electron-builder is the primary build tool.

Alternatives

Software Packaging Tools is a useful directory for comparing packaging options. Choose Tauri Bundler instead if you want an open-source Rust library that wraps Rust executables in OS-specific app bundles and can target mobile as well as desktop; its public API stability is not strictly SemVer. InstallAware may suit Visual Studio users looking for a freeware edition that permits commercial use, though it requires Visual Studio.

IzPack is another free, Apache License 2.0 option. NSIS may fit projects focused on Windows installers, including installers up to 2GB, while remaining free for any use. Advanced Installer is an option for Windows-only projects whose needs fit its freeware Simple-project features.

For Linux-only packaging, consider Flatpak Builder. fpm is a command-line package builder and converter, though some output formats require optional system tools. WiX Toolset is another option for Windows-focused installer work.

Verdict

Choose electron-builder if you ship Electron apps across desktop platforms and want broad output formats, configurable updates and security options in one release workflow, without paying for the tool. Its chief trade-off is operational: signing and native dependencies impose platform-specific build requirements. Teams willing to plan for those constraints get a versatile packaging choice; those seeking visual authoring or simpler platform boundaries should compare alternatives.
