Are you talking about Tableau Server? If so, refer here for specifics of the licensing models. But the basic answer is yes; unless your content is of public nature, then you may be able to publish to "Tableau Public" after you signup for a free public account.
If you're talking local on a user's desktop, then there is a product that is called "Tableau Reader" that is free and allows consumers to view / I think interact with content. But they need to have access to the workbook locally.
I have a Tableau Sever account, I guess I just need to add users with read only access? Of course I'm assuming this means they don't need a license just a login credentials for viewing. Do you know if I'm assuming correctly?
Users don't need a local license if this is what you're getting at. But the server does need to be licensed properly. Server core based license allows as many users as you want and is only limited by capacity (i.e. CPU) of the server that you're installing onto. Server named user licensing allows you to have specific named users up to the limit of how many named users within server is permitted via the license that you purchase. In either model, the users do need to be defined by the admin of server (via the interface). And if you do happen to have core based licensing, then guest user access is an option too for embedded anonymous access. Guest User
Does this help more?
Thank you Jeff. Very helpful. I just contacted our admin.
