Does AlertForge work with OBS?

Yes. Paste your generated overlay URL into OBS Browser Source, or use transparent WebM exports.

How fast can I create a full alert pack?

Most creators can build a full follow, sub, and donation pack from one template in a few minutes.

Can I keep consistent branding across every alert?

Yes. Reuse one visual style, font system, and motion style across all alert types.

Can I download the sound effect separately?

Yes. You can download alert sound effects separately for your stream setup.

Is AlertForge free to use?

Yes. You can create and export Twitch alerts for free. Premium credits are available for AI video generation and bulk alert packs.

What export formats does AlertForge support?

AlertForge exports transparent WebM files with alpha channel support, perfect for OBS Browser Source overlays. You can also use hosted overlay URLs directly.

Can I animate my own logo as a Twitch alert?

Yes. Upload any PNG image or logo and AlertForge will animate it as a stream alert with AI motion, transparent background, and text overlays.

Does AlertForge work with YouTube and Kick?

Yes. AlertForge exports transparent WebM files and hosted overlay URLs that work with any streaming platform through OBS, including YouTube Live, Kick, Facebook Gaming, and Twitch.

How is AlertForge different from StreamElements or Streamlabs alerts?

StreamElements and Streamlabs provide alert widget overlays. AlertForge is an alert creation tool — you design and animate unique alert visuals with AI, then use them in any alert widget system including StreamElements and Streamlabs.

Can I use AlertForge alerts with StreamElements?

Yes. Export your alerts as transparent WebM files and upload them as custom alert media in StreamElements or Streamlabs.

What makes AI-generated alerts different from template alerts?

AI-generated alerts use motion synthesis to create unique animations from your prompt and style direction. Template alerts use pre-made designs that many other streamers also use.

What you get

One prompt. A complete stream identity.

Scenes, panels, labels, sub badges, emotes, alert videos, a stinger, cam frame and design sheet all share the same character, palette and mood, so your stream finally looks like one brand instead of five free downloads.

The pack's design sheet — character reference and the exact color palette used across every file

The source of truth

Every file traces back to one design sheet

Character, typography and palette are locked on the sheet first — then every scene, badge, emote, alert and the stinger are generated against it. That's why the whole pack reads as one brand.

I used to spend hours in After Effects for one alert. AlertForge gave me a full branded pack in 10 minutes. My chat noticed immediately.
