How do I add AlertForge alerts to OBS?

Add a new Browser Source in your OBS scene, paste your AlertForge overlay URL, and set dimensions to 1920x1080. Test with the alert button to verify placement. Takes less than 5 minutes.

What's the difference between Browser Source URL and WebM files?

Browser Source URLs auto-trigger when events occur on your stream with zero maintenance. WebM files give you offline control and work with any alert widget system like StreamElements or Streamlabs.

Do AlertForge alerts work with all streaming platforms?

Yes. AlertForge OBS alerts work with Twitch, YouTube Live, Kick, and Facebook Gaming. The transparent WebM format and Browser Source URLs are universally compatible.

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.
