As-Is
Tableau does not actively monitor as-is tools for feedback and makes these tools available with no support. If you have any issues, you may ask for help on the Tableau community forums.
Community-Supported
Tableau will periodically review comments, requests and address feedback of Community-supported tools. If you have any issues, you may ask for help on the Tableau community forums or log any defects that you discover in the tool's issue tracker. Services offerings may be available on a tool by tool basis; your Account Manager can assist with scheduling Services engagements.
Tableau-Supported
Tableau provides support for potential defects, and for unmodified sample code that isn't working. For help with your code, submit questions and ask for help on the Tableau developer community forums or log any defects that you discover in the tool's issue tracker. If you are a Tableau customer, you can contact Tableau Support for assistance with errors in the sample code provided by Tableau. However, Tableau does not provide support for programs that customers create that use a specific tool. Services offerings may be available on a tool by tool basis; your Account Manager can assist with scheduling Services engagements.
