Manage App Distribution testers

You can manage your project's testers in the Testers & Groups tab of the App Distribution page (in the Firebase console). This tab allows you to:

  • Add new testers (you can also add new testers when you set up a distribution).
  • Import testers from CSV files.

    The CSV file must contain the tester's email address. It can also contain the tester's name (optional) in the same row. For example:,Ali Smith
    Cal Nguyen,
  • Assign testers to groups. For example, you could create one group for your iOS testers and another for your Android testers. You can then invite all of a group's members to test a new build.
