Tableau Viewer vs. Tableau Reader
What is the difference between Tableau Reader and Tableau Viewer?
In short, a lot.
Tableau Reader is a free product that was created in the early days of Tableau to allow analysts and content creators to distribute content they built in Tableau Desktop. This was before Tableau Server was made available to organisations to govern the sharing and distribution of analytics content. At the time, Tableau Reader was the only option for sharing interactive content with other users in an organisation without access to Tableau Desktop.
Tableau Viewer is a role-based licence option on Tableau Server which allows casual users to access and interact with trusted content created by creators and explorers without putting the security of your data at risk.
In terms of functionality, Tableau Reader lacks the governance, security and administration capabilities which are essential for mission-critical production deployments of Tableau. In addition, Tableau Reader users can only access and interact with local workbooks (see the comparison chart below for a detailed product comparison). These product limitations make Tableau Reader an appropriate option for some proof-of-concept projects, but the wrong choice for deploying analytics at scale across your organisation.
Tableau Viewer users, on the other hand, benefit from the security and trust that comes with a governed server-based deployment and specifically can:
- Access and interact with embedded, web-based and mobile content
- Download underlying summary data for a visualisation
- Favourite content
- Download visualisations as image files (PNG, PDF)
- Comment on a visualisation or dashboard
- Create and receive subscriptions
- Receive data-driven alerts
Is Tableau Reader really free?
Tableau Reader is a free software download but it is not free to deploy and maintain if used as an alternative to Tableau Server. Organisations must consider the significant cost associated with valuable IT resources deploying and supporting a Tableau Reader deployment. There is also the potential cost of compliance issues associated with the lack of governance in Tableau Reader. Tableau Reader deployments require source files to be shared and accessed locally, which means that IT has no visibility into where the files go or how they are used after they are created.
The role-based server licences offered by Tableau empower IT to secure, govern and administer a production deployment while significantly reducing the risks and hidden costs that an organisation is exposed to when trying to deploy Tableau Reader at scale. Information on how to choose the mix of Tableau Server roles that are right for your organisation can be found here.
How do you migrate from a Tableau Reader deployment to Tableau Server?
If you already have a Tableau Reader deployment that is growing out of control, you should consider the benefits that Tableau Server will offer. The first step when considering a migration from Tableau Reader to Tableau Server is to take inventory of your current usage. Determine how many users, workbooks and data sources comprise your Tableau Reader deployment. The next step is to quantify the cost of managing the deployment based on the inventory of users and content.
How much does it cost to manage and distribute this content, and what is the opportunity cost associated with IT not doing more strategic work for your organisation? The impact on business processes should be determined next, with a focus on how much more value can be unlocked by sharing and collaborating around shared content available on Tableau Server. Finally, make the case for investing in Tableau Server and move Tableau Reader content to a governed environment where your users can experience the full power of Tableau.
