We are interested in having viewers and interactors on our server. Are there different licenses for viewers and interactors that can be purchased separately? Assumption being that a viewer license is less expensive due to reduced functionality?
All users on Tableau Server must be assigned a license level, even if it is that they are Unlicensed. License Levels control how much access the user has on the server. This is a summary of the differences between Viewer and Interactor license levels on Tableau Server.
Note: These capabilities are allowed by default with each license level. Additional permissions can be added to specific views, workbooks, and projects.
