Free. Powerful. Fully Customizable.

We believe game developers deserve another choice. That’s why we’re building Lumberyard: a game engine with no royalties or seat fees, frictionless integration with Twitch and AWS, plus much more on the horizon.

Build Bigger

Lumberyard is architected for performance, modularity, and productivity. Reduce time to quality and maximize ambition, across PC, console, and mobile.

Build a Fanbase

Engage and grow your community inside and outside of your game, and build games as fun to watch as they are to play, with Lumberyard's Twitch integration.

Build Free

Lumberyard is free and includes full source. There are no seat fees, subscription fees, or requirements to share revenue. Only pay for the AWS services you choose to use.


Amazon Lumberyard is the only AAA game engine that equips you with a combination of feature-rich development technology, native integration to the AWS Cloud, and native integration of Twitch features. Plus, it's completely free.

Twitch ChatPlay

The Twitch ChatPlay feature in Lumberyard helps you build gameplay that interacts in real time with Twitch viewers. For example, you can build a game where spectators vote on game outcomes, gift power-ups to their favorite players, or change the level based on the number of viewers watching the broadcaster. Using Lumberyard’s scripting tools, you can easily create chat channel commands for your game. For example, you can build a multiplayer game where viewers vote to drop grenades to the broadcaster by typing #boom in the Twitch chat channel.

Twitch Metastream

The Twitch Metastream feature in Lumberyard allows Twitch streamers to deeply customize broadcasts of your game. When you add Twitch Metastream to your game, streamers can use any HTML tool to create and display dynamic real-time graphics based on the data you provide, similar to those used in professional esports and television broadcasts. For example, overlays can include minimaps, objective status, and player stats that update based on game events. Adding Twitch Metastream to your Lumberyard game is simple – just enable the Metastream Gem for your project and add a single line of code for each piece of data you want to expose.

Twitch JoinIn

The Twitch JoinIn feature in Lumberyard lets you build multiplayer games that allow Twitch broadcasters to invite fans to join them side-by-side in the game. Once invited, a fan can jump into the broadcaster’s game with a single click in the Twitch chat channel, while others continue to watch.

Mod Friendly

Games that support mods and user-generated content have extended lifespans, increased social media exposure, and increased player retention. Lumberyard is mod friendly – you can include components from Lumberyard Editor in your games so your end users can create content with the same tools that you use.
