Twitch is a streaming platform where you can stream videos in various categories, such as Music, Games, Talk Shows, Travel, Sports, Food, and Special Events. The best part of Twitch is that it supports multiple devices. Though Twitch is free, you can subscribe to the plans for the premium features, such as emotes and more.
