Collaborators, or application editors, are the number of unique Bubble accounts that can access your app's editor. The number of collaborators that can be added to your app depends on your app's plan. On the Free and Starter plans, only one developer is allowed: the app's owner. On Growth and above, you can invite additional collaborators to your application to have them work on the app.
Please note that we cannot add a la carte collaborators to an app's plan.
