Publish preview updates

Edit this page

Learn how to publish preview updates with EAS Workflows.

Once you've made changes to your project, you can share a preview of your changes with your team by publishing a preview update. This is useful when you want to review changes with your team without pulling the latest changes and running them locally.

You can access preview updates in the development build UI and through scannable QR codes on the EAS dashboard. When publishing a preview on every commit, your team can review changes without pulling the latest changes and running them locally.
