EAS Build

EAS Build is a hosted service for building app binaries for your Expo and React Native projects.

EAS Build is a hosted Expo Application Services (EAS) service that builds app binaries (also called standalone apps) for your Expo and React Native projects.

EAS Build makes building your apps for distribution simple and easy to automate by providing defaults that work well for Expo and React Native projects out of the box, and by handling your app signing credentials for you (if you wish). It also makes sharing builds with your team easier than ever with internal distribution (using ad hoc and/or enterprise "universal" provisioning), deeply integrates with EAS Submit for app store submissions, and has first-class support for the expo-updates library.

EAS Build is also designed to work for any native project, whether or not you use Expo and React Native. It's the fastest way to get from npx create-expo-app or npx @react-native-community/cli@latest init to app stores.

Quick start

To build your app, run the following command:

This command sends your project to EAS Build and produces installable binaries for Android and iOS. You can also build for one platform at a time by passing in --platform android or --platform ios as desired. For complete setup instructions, see Create your first build.

Key features

• Cloud builds for Android and iOS with consistent environments
• Automatically provision and manage app signing credentials or use your own
• Share internal distribution builds with a URL
• Automate builds with build profiles in eas.json (named sets of build settings) and integrations with EAS Workflows or CI pipelines
• Auto-submit successful builds to app stores via --auto-submit and EAS Submit
• First-class expo-updates integration with per-profile channels and runtime version guidance
• Reuse development builds across your team. When two team members run eas build:dev and the project fingerprint matches, the existing build is downloaded from EAS instead of creating a new one
• Faster builds via dependency caching and custom cache paths
• Install builds and updates on devices with Expo Orbit
