Making a GitHub App public or private

When setting up a GitHub App, you can make its installation public so any GitHub user or organization can install the app, or private so you can only install it on the account that created it.

Public installation flow

Public installation flows have a landing page where users begin the installation flow. This link is provided in the "Public link" field when setting up your GitHub App. For more information, see "Installing GitHub Apps."

Private installation flow

Private installation flows allow only the owner of a GitHub App to install it. Limited information about the GitHub App will still exist on a public page, but the Install button will only be available to organization administrators or the user account if the GitHub App is owned by an individual account. Private, or internal, GitHub Apps can only be installed on the user or organization account of the owner.
