Twitch just launched their own version of Alerts that is addable as a browser source through your streaming software. This supports the typical events, followers, subscriptions, and more.

Seems pretty well thought out, I recommend checking out the links below for more information.

Anyone has access, you just can only setup alerts for what you are. if you’re not an affiliate, you’ll only have the basic ones, i.e. follower.
