To learn more, see\n[Add and remove testers from a group](#add-remove-testers-group).\n\nTester limits\n\nFirebase App Distribution has the following tester limits:\n\n- Add a maximum of 500 testers to a Firebase project\n\n- Add a maximum of 200 testers to an App Distribution group\n\nTo add more testers, request a no-cost\n[limit increase](https://console.firebase.google.com/project/_/appdistribution/limits).\n\nAdd and remove testers with the Firebase App Distribution API\n\nYou can use the `testers.batchAdd` and `testers.batchRemove` endpoints in the\n[Firebase App Distribution API](/docs/reference/app-distribution/rest)\nto add or remove testers from App Distribution using an HTTP request to the\nApp Distribution API.\n\nAdd and remove testers from a group\n\nYou can add and remove testers from groups in the **Testers \\& Groups** tab of\nthe [App Distribution page](https://console.firebase.google.com/project/_/appdistribution)\nin the Firebase console. Groups are useful for managing access to releases\nfor a large number of testers. For example, you could create a group to grant\na small group of testers access to an early release of an app. Once you\nimplement feedback from the initial tester group, you can create a\ngroup for a larger number of testers.\n\nWhen you add or remove testers from a group, those testers gain or lose\naccess to *all of the releases* which were distributed to that group.\n\nRemove a tester from a group\n\nWhen you remove a tester from a group:\n\n- The tester is removed from *all* releases that they had access to *exclusively* via the group from which they were removed.\n- If the tester is a member of a different group which also has access to a release, the tester retains access to that release.\n\nDelete a group\n\nWhen you delete a group, all of the testers in that group are removed from all\nreleases that they had access to exclusively via that group. In most cases,\ngroup deletion occurs almost immediately; but if you have a large number of\ntesters and releases, the group delete can take longer. After you\ndelete a group, it is no longer listed in the App Distribution page of the\nFirebase console.\n\nDeleting a group may not take effect immediately; after you\ndelete a group you might temporarily see individual testers from the deleted\ngroup listed as having access to a specific release.\n\nNext steps\n\n- [Import testers from CSV files](/docs/app-distribution/import-testers-csv-files).\n\n- To learn how to increase your internal testing base, see [Create invite links](/docs/app-distribution/create-invite-links).\n\n- To register additional iOS devices manually or programmatically, see\n [Register additional iOS devices](/docs/app-distribution/register-additional-devices)."]]
