Power BI report server - Developer Edition????

Folks: 

Is anyone aware of a Power BI Report Server - Developer Edition of the like?  I am just starting an evaluation project - we are standing up infrastructure now.  I have a subscription to VisualStudio.com.  That is typically where I would get software for such an adventure.  But I do not see Power BI Report Server available there.  In addition - I would like to run the thing on my laptop - just as I run SQL Server Developers edition.

The only thing I can find out there is the 180 day evaluation which will meet our evaluation needs - but longer term developmet??  That will not work. 

Any ideas??
