Vortexia is a free WebGL music visualizer that runs entirely in your browser. It renders real-time, GPU-accelerated fractal visuals that react to bass, mid, and treble frequencies — built for streamers, DJs, and live performers.
Vortexia is a WebGL music visualizer: every frame is computed on your graphics card by a fragment shader running in the browser, with no plugin and no install. That matters for what it can do rather than as a buzzword. Because the maths runs per pixel on the GPU, the shapes are genuine fractals evaluated live — a Mandelbrot iteration, a Julia set, a Burning Ship, or a raymarched 3D Mandelbulb — rather than a video loop or a bar-graph spectrum drawn on a 2D canvas. Nothing repeats, and you can zoom to 100,000x magnification while it is running. Audio arrives through the Web Audio API as a 128-bin frequency spectrum, uploaded to the GPU as a texture every frame, so the shader can read individual bands: bass drives the pulse and zoom, mids morph the geometry, treble affects colour and chromatic aberration. That per-band split is what separates it from a visualizer that simply scales everything with volume, where a kick and a cymbal of equal loudness look identical. Everything is local — the audio never leaves your machine and there is no server round trip, so the picture moves with the sound. It needs WebGL2, which every current version of Chrome, Edge, Firefox and Safari supports. Free at 720p with a small watermark; Plus is $4.99 a month.
How to use GPU-Accelerated Music Visualizer
Open it and enable audio. Go to vortexia.live, grant microphone access or route system audio in, and the visual starts reacting immediately.
Choose an engine. Six 2D fractal engines plus two raymarched 3D ones. Rhythm locks to kick drums; Flux follows melody.
Send it to your stream. Copy the OBS link from the dashboard and paste it into a Browser Source at your canvas size.

Frequently asked questions
What does WebGL actually change here?
It lets the fractal be computed per pixel on your GPU in real time. Most browser visualizers draw a spectrum or a waveform on a 2D canvas, or play a pre-rendered loop. Here the shape is being solved every frame, which is why it can zoom indefinitely and never repeat.
Does it need a powerful graphics card?
No. The 2D engines cost roughly 1ms per frame at 1080p on ordinary hardware — integrated graphics handle them comfortably. The two 3D raymarched engines are about ten times heavier, which is why they are capped at 720p.
Is my audio uploaded anywhere?
No. The FFT runs in your browser and the spectrum is passed straight to the GPU. Nothing is transmitted, stored or analysed on a server, which is also why there is no perceptible delay between the sound and the picture.
Which browsers work?
Anything with WebGL2: current Chrome, Edge, Firefox and Safari, on desktop and mobile. If WebGL2 is unavailable the page says so rather than showing a blank screen.
Can I use it in OBS?
Yes — that is the main use. Copy your viewer URL into an OBS or Streamlabs Browser Source at 1920x1080. It is the same page, so it keeps full GPU rendering and audio reactivity inside your stream.
