electron-builder

Overview

electron-builder takes an Electron app through packaging and toward distribution, with installers, portable builds, and archives for three desktop platforms. Its range is useful when a project needs multiple ways to install or distribute the same app. Teams wanting a visual installer-authoring environment should look elsewhere; this is a command-line packaging tool.

Release work can extend beyond producing artifacts: electron-updater supports updates, and configured providers can receive releases. Publishing in v27 must be explicitly requested through a CLI flag or configuration option, a useful safeguard against an accidental release.

Key features

Packaging formats

Outputs include macOS DMG, PKG, and MAS; Linux AppImage, Snap, DEB, RPM, and other package formats; and Windows NSIS, MSI, AppX, and MSIX. Portable EXE builds and archives such as ZIP and 7z add options for users who do not need a conventional installer. Silent installation is supported, which can help with unattended deployment. This breadth is a practical advantage for teams serving different operating systems and distribution needs, though choosing and maintaining the right targets still requires build configuration.

Updates and release controls

electron-updater supports differential updates, which can reduce the amount of data users need to download, as well as staged rollouts. Documented providers include GitHub Releases, Amazon S3, DigitalOcean Spaces, Cloudflare R2, Keygen, and generic HTTP(S) servers. Update manifests can optionally be signed with Ed25519 and checked against a public key embedded in the app before downloads. That gives teams a way to add verification to the update path; it is optional configuration rather than a default requirement.

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 controls are useful for teams preparing a more deliberate release, but they do not remove the need to manage signing credentials and platform-specific build environments.

Automation and Forge

The documentation provides GitHub Actions CI/CD guidance for building and publishing. Electron Forge maker packages can create electron-builder targets, but publishing, auto-updates, and code signing require electron-builder to be the primary build tool. That distinction matters for teams already using Forge: it can reuse the packaging targets, but not the full release workflow as a secondary tool.

Pricing

electron-builder is open source and free. The electron-builder plan costs 0.00 USD per free, with no paid plans stated. There are no listed seat limits, quotas, trial periods, or renewal terms to weigh; the practical cost is in configuring and maintaining release builds, especially where signing and native modules are involved.

Platforms

electron-builder targets macOS, Windows, and Linux, with formats including DMG, PKG, MAS, AppImage, Snap, DEB, RPM, NSIS, MSI, AppX, and MSIX. The main constraint is that macOS code signing works only on macOS. Native dependencies generally also need to be compiled on their target platform unless prebuilt binaries are used, so a single build machine may not cover every release target reliably.

Who it's for

Choose electron-builder if you maintain an Electron app for multiple desktop platforms and want packaging, signing support, and update workflows in a command-line tool that can fit into CI. It is less suitable if your workflow depends on building macOS-signed releases from another operating system, or if you need visual installer authoring. Teams using Electron Forge can use its maker packages for targets, but should make electron-builder the primary tool when publishing, updates, or signing are part of the job.

Pros and cons

• Pros: A wide set of installer, portable, and archive outputs lets one Electron project serve different desktop distribution needs.
• Pros: Differential updates, staged rollouts, multiple providers, and optional manifest signing support a configurable release pipeline.
• Pros: ASAR integrity hashes are on by default, with Electron Fuses available to disable selected features at package time.
• Cons: macOS signing requires macOS, while native dependencies generally need target-platform builds or prebuilt binaries; cross-platform release planning takes care.
• Cons: Forge can create targets through maker packages, but publishing, auto-updates, and signing require electron-builder as the primary build tool.

Alternatives

Compare software packaging tools if you are still deciding which kind of packaging workflow fits your project.

• Tauri Bundler is a free open-source Rust library for wrapping Rust executables in OS-specific bundles; consider it when your app is built around Rust rather than Electron. Its public API stability is not strictly SemVer.
• InstallAware offers a free Visual Studio edition for commercial use; consider it if Visual Studio is already central to your workflow.
• IzPack is a free Apache License 2.0 option for packaging across Windows, macOS, Linux, and self-hosted environments; consider it if that licensing and platform mix suits your project.
• NSIS is free for any use, supports installers up to 2GB, and generates installers that run on Windows; consider it for Windows-focused installer creation.
• Advanced Installer has a freeware tier for simple projects; consider it if your needs fit its freeware features and your target is Windows.
• WiX Toolset keeps its source code freely available; consider it if you want a source-based Windows packaging option.
• Flatpak Builder is a free Linux option with no paid plans or usage limits stated; consider it for Linux-only packaging.
• fpm provides command-line package building and conversion, with some formats requiring optional system tools; consider it if package conversion is the priority.

Verdict

For teams distributing Electron apps across macOS, Windows, and Linux, electron-builder is a strong choice: it combines broad packaging targets with configurable update and release controls at no cost. Look elsewhere if your build environment cannot accommodate macOS signing or target-platform native dependencies, or if you need a visual installer workflow.
