Twitch has turned the live streaming experience upside down, and they partnered with AWS and challenged the community to elevate the streaming experience with Twitch Extensions powered by AWS tools. Extensions are apps that can interact with live streams as a panel on a channel or a video overlay, making a fully interactive experience between content creators and their viewers.

Participants created extensions to make community interaction and engagement even better!

The Twitch Extensions sandbox is a web-based WYSIWYG editor that makes it easy for developers to build and ship Extensions with robust samples and real-time testing on a live channel. Combine this with AWS integrations and the possibilities of what to test and build grow exponentially.
