SharePoint for 2016 Free templates have now been available for download and are available to download for free on the SharePoint web site.
SharePoint templates for 2016 can be found on the Microsoft website as well.
The templates were released at the same time as the upcoming update for SharePoint that will bring the Sharepoint 2016 Free template for download to the Office 365 and Windows Server 2016 editions of SharePoint.
SharePoint templates have been available on the web for some time, but the free version was made available on April 10, 2017.
As of today, the Sharepoints 2015 free templates are also available to use.
The free templates were created by Microsoft and published by SharePoint Inc. to help developers create SharePoint sites that could be used on Microsoft Office 365, Windows Server and SharePoint Online.
