1. How about an extension that helps you pick the best builds and items based on how the game is going?

2. One that gives viewers the power to force their streamer to jump the plane in a battle royale game?


3. Perhaps an extension that enables predicting streamer results and delivers donations to their channel on the condition they meet the viewer challenge?

If it links streams to in-game kills, deaths and other events - you can now develop it. Don't hold back!

To get you started, we have gathered extension ideas from our community:
