Amazon Lumberyard is a free cross-platform game engine developed by Amazon and based on CryEngine, which was licensed from Crytek in 2015. The engine features integration with Amazon Web Services to allow developers to build or host their games on Amazon's servers, as well as support for livestreaming via Twitch. Additionally, the engine includes Twitch ChatPlay, allowing viewers of the Twitch stream to influence the game through the associated chat, a method of play inspired by the Twitch Plays Pokémon phenomenon. The source code is available to end users with limitations: Users may not publicly release the Lumberyard engine source code or use it to release their own game engine. Lumberyard launched on February 9, 2016 alongside GameLift, a fee-based managed service for deploying and hosting multiplayer games, intended to allow developers the easy development of games that attract "large and vibrant communities of fans." As of March 2018[update], the software is currently in beta status and can be used to build games for Microsoft Windows, PlayStation 4, Xbox One, with limited support for iOS and Android and the support of Linux and Mac being planned for future releases.Virtual reality integration was added in Beta 1.3, allowing developers to build games supporting devices like Oculus Rift and HTC Vive.
