Note: This isn&#x27;t Open Source, though the source code is available.<p>&gt; Q. Is Lumberyard “open source”?<p>&gt; No. We make the source code available to enable you to fully customize your game, but your rights are limited by the Lumberyard Service Terms. For example, you may not publicly release the Lumberyard engine source code, or use it to release your own game engine.<p>What&#x27;s really interesting is that you can&#x27;t use Lumberyard to communicate with game servers if they are hosted on a competing cloud platform; only AWS or server hardware you own:<p>&gt; Q. Can my game use an alternate web service instead of AWS?<p>&gt; No. If your game servers use a non-AWS alternate web service, we obviously don’t make any money, and it’s more difficult for us to support future development of Lumberyard. By “alternate web service” we mean any non-AWS web service that is similar to or can act as a replacement for Amazon EC2, Amazon Lambda, Amazon DynamoDB, Amazon RDS, Amazon S3, Amazon EBS, Amazon EC2 Container Service, or Amazon GameLift. You can use hardware you own and operate for your game servers.
