What is EAS Build?

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

🚀 Using this has the following advantages.

  1. It’s very easy to build apps for deployment by processing signature credentials.
  2. You can include libraries with native code that aren’t part of the Expo standard library
  3. You can reduce the app capacity.
  4. You can easily share test builds with colleagues without going through the app store.
  5. You can build all platforms with just one command.

If one of the above reasons is considered convenient, it is sufficient to use the EAS build.


  1. EAS build is a paid service. You have to pay Priority plants from your Expo account.

The first month is free and as of November 4, 2021, you have to pay $29 a month.

Please check the link below for the detailed cost.

2. An Expo account and Android and iOS developer accounts are required.

3. Support for Expo managed projects is available as of SDK 41
