On-screen alerts for every follow, sub, gift and raid
Give every new follower, subscriber, gifted sub and raid a moment on screen. The Alert Box widget pops up an animated, customizable message the instant the event happens, so nothing goes unnoticed by you or your chat.

Why streamers use it
Covers every event type
Follows, subs, gift subs and raids all get their own rule and message template.
Custom message templates
Write your own alert text with the viewer's name inserted automatically.
Real-time triggers
Alerts fire the moment the event happens on Twitch or YouTube, no delay.
Setting it up
Alert Box takes about two minutes to get on screen: create it in the dashboard, copy the URL, add a Browser Source. The full guide has the exact size to use and what to do when it doesn't appear.
Read the Alert Box setup guide →Alert Box: common questions
Is Alert Box free?+
Yes. Every plan includes one Alert Box widget, live updates and the default look included. Creator+ adds unlimited widgets of every type, plus full styling, animations and the premium templates.
What Browser Source size should I use for Alert Box?+
Start at 1920 × 1080 pixels, set in the source properties rather than by scaling the source in your scene — the widget fits itself to whatever box it is given.
Does Alert Box work with Streamlabs and XSplit?+
Yes. Alert Box is a normal web page, so it works in any streaming software with a browser or web overlay source — OBS Studio, Streamlabs, XSplit and the rest.
How long does Alert Box take to set up?+
A couple of minutes. Create it in the dashboard, copy its URL, paste it into a source. Styling can happen later, live, without touching OBS again.
Do I need to install a plugin?+
No. There is nothing to download and no plugin to keep updated — Alert Box is one URL, and it updates itself on our side.
