Amazon Lumberyard

Amazon Lumberyard is a free, cross-platform, 3D game engine for you to create the highest-quality games, connect your games to the vast compute and storage of the AWS Cloud, and engage fans on Twitch.

Amazon Lumberyard is free, including full source code, so you can deeply customize Lumberyard for your team and your vision for your project today, and for future projects in years to come. There are no seat fees, subscription fees, or requirements to share revenue. You only pay for the AWS services you choose to use.

Lumberyard provides free access to its native C++ source code.

Real-time gameplay editing enables you to iterate on gameplay and immediately see your results, without waiting for builds or leaving the editor.
