In Zoho Creator, a user is an individual who has access to a Zoho Creator workspace. This can be anyone within an organization. They can access and add data on the application.
We don't offer separate licence for developers of the app. In simple terms, it doesn't matter if you are the application owner or an app user, as both are considered named users who need to subscribe to the platform. For example, if you are the owner/admin of the app (person who built the app) and you need to share the app with three users of your organization, then you need to buy four user licence.
