What is A Music Visualizer That Reacts to Your Twitch Channel?
Vortexia is a free music visualizer for Twitch that reacts to two things at once: the music you are playing, and what happens on your channel. Add it to OBS or Streamlabs as a single Browser Source and it moves with your audio, with bass, mids and treble each driving part of the motion. Connect Twitch in the dashboard and it also reacts on its own when someone follows, subscribes, gifts subs, cheers bits, raids you or starts a hype train, and each event gets its own treatment, so a raid does not look like a follow. An audio visualizer cannot know a raid happened, and an alert widget draws a card in a corner; this changes your whole background. Twitch is on the free plan, which streams at 720p and 30fps with a small watermark.
How to use A Music Visualizer That Reacts to Your Twitch Channel
Add it to OBS. Copy your OBS link from the Vortexia dashboard and add it as a Browser Source.
Connect Twitch. In the dashboard’s Platforms tab, connect Twitch so channel events reach the visual.
Choose what it listens to. Leave it on Microphone, or pick Music / system to capture your music directly.
Keep the dashboard open. The dashboard tab listens to your audio while you stream. It can be minimised, not closed.

Frequently asked questions
Which Twitch events does it react to?
Follows, new subscriptions and renewals, gifted subs, bits, raids, and hype trains from start to finish. Each has its own effect and intensity, and a hype train holds its effect for as long as the train runs.
Do I need to install anything?
No plugin and no download. Vortexia is a web page: you add its URL to OBS or Streamlabs as a Browser Source, and connect Twitch once in the dashboard.
Can I fire effects myself, from a Stream Deck?
Yes. The dashboard has buttons and Shift+Alt+1 to 6 for sub, donation, raid, hype train, bits and follow, and trigger links let a Stream Deck, Touch Portal or Streamer.bot button fire an effect while OBS or a game has focus.
Will it react to music I hear through headphones?
Yes, once you set Listening to Music / system in the dashboard, which captures your desktop or a browser tab directly in Chrome or Edge on Windows. The default is the microphone, which only hears what reaches the room.
Is it free?
Yes. The free plan streams at 720p and 30fps with a small watermark, three engines and Twitch. Plus removes the watermark, renders at 1080p and 60fps, unlocks all eight engines and adds automatic YouTube and Kick events.
