How do I add AlertForge alerts to OBS?

Download the transparent WebM, add a Media Source in OBS, select the file, and position it in your scene. For automatic platform-event triggers, upload the same file to a connected alert widget such as StreamElements or Streamlabs.

What's the difference between an OBS Media Source and an alert widget?

A Media Source plays a local WebM in OBS. A connected alert widget can use that WebM as custom media and decide when to trigger it for platform events.

Do AlertForge alerts work with all streaming platforms?

The exported WebM is platform-neutral and can be used in OBS regardless of where you broadcast. Automatic event triggering depends on the platform connection provided by your alert widget.

Do I need special OBS plugins for AlertForge alerts?

No. AlertForge exports transparent WebM files that OBS handles natively. No plugins, no extra software, and no complicated setup required.

Setup

Two ways to use them in OBS.

Alert widget (automatic)

Recommended

Upload each WebM to StreamElements or Streamlabs and link it to an event. The widget plays the right alert when someone follows, subs, or donates.

01Upload the WebM as custom alert media
02Pick the event it plays for
03Add the widget to OBS as a Browser Source

Media Source (manual)

Simple

Add the WebM straight into an OBS scene. Great for intros, reactions, and anything you trigger yourself.

01In OBS, add a Media Source
02Choose the WebM file
03Position it and play it when you want

A Media Source only plays when you tell it to. For alerts that fire on follows and subs automatically, use an alert widget. Step-by-step guides: Twitch, YouTube, Kick.
