Super Chat alerts
A celebration worthy of the viewers who support you with Super Chats.
YouTube alerts
Turn your logo or mascot into animated alerts for new members, Super Chats, Super Thanks, and subscribers. Every alert shares your look, and downloads as a transparent WebM for your alert widget.
Works with OBS, StreamElements, and Streamlabs.


Made with AlertForge
Real alerts from AlertForge packs, shown on a checkerboard. Every file is a transparent WebM, so only your alert appears on stream.



What you can make
A celebration worthy of the viewers who support you with Super Chats.
Welcome channel members with an alert starring your character.
A custom thank-you animation for Super Thanks.
A friendly moment when someone subscribes during your stream.
Use the files with StreamElements, Streamlabs, or any widget that connects YouTube to OBS.
Every alert is a transparent WebM you download and own.
How it works
Upload your logo or mascot, or describe one. Approve a free style sheet and it becomes the star of every alert.
Choose the YouTube Live moments you want alerts for. You see the credit cost before you generate.
Watch every alert, redo any you don't love, and keep the ones you do.
Upload each WebM to StreamElements or Streamlabs, link it to the YouTube events your widget supports, and add the widget to OBS.
To play alerts automatically, connect your channel to an alert widget, upload your WebM files, and add the widget to OBS as a Browser Source. Read the YouTube setup guide.
