Grit & Glitch: The Phonk Visual Engine — High contrast black and white with red accents. Vortexia generates sharp, dark, glitch-leaning fractals tuned for low-end energy, tuned for this style of music. The Bass Tunnel engine runs on WebGL in your browser, listens to the audio your stream is already playing, and renders a 1080p (or 4K on Pro) visual layer in real time. To use it on a stream, copy the viewer URL into OBS, Streamlabs and any other broadcasting software as a Browser Source — there is nothing to install and no plugin to update. The visualizer reacts to bass, mid and treble bands separately, so kick drums, leads and atmospheric pads each drive their own motion. You can also customize colour shift, zoom and iteration depth from the dashboard, save the result as a preset, and reuse the same URL across every show.
How to use Grit & Glitch: The Phonk Visual Engine
Customize the visual. Open the Vortexia dashboard, choose the Grit & Glitch: The Phonk Visual Engine preset, and adjust colour shift, zoom and iteration depth until it matches your show.
Copy the viewer URL. Click "Get Browser Source URL" — Vortexia will give you a permanent URL that loads this exact configuration anywhere.
Add it to OBS, Streamlabs and any other broadcasting software. In OBS, Streamlabs and any other broadcasting software, add a new Browser Source, paste the viewer URL, and set the canvas to 1920×1080 (or 1080×1920 for vertical). The visual is live as soon as the source loads.
Route your audio. Make sure the browser tab can hear the audio you want it to react to — most streamers route their stream output through a virtual audio cable so Vortexia and OBS hear the same mix.

Frequently asked questions
Is Grit & Glitch: The Phonk Visual Engine really free?
Yes. The free tier of Vortexia runs at 720p with a small corner watermark, on a single platform. Plus ($49.99/year) removes the watermark at 1080p/60 across multiple platforms, and Pro ($119.99/year) ships 4K/60 with custom shader uploads. There is also a $149 one-time lifetime licence.
How do I add Vortexia to OBS, Streamlabs and any other broadcasting software?
Open the Vortexia dashboard, customize the visual, click "Get Browser Source URL" and copy it. In OBS, Streamlabs and any other broadcasting software, add a Browser Source, paste the URL, set the canvas to 1920×1080 (or 1080×1920 for vertical), and the visual is live. Audio reactivity uses the audio Vortexia hears — most streamers route their existing stream output to the browser tab.
Does it actually react to the music or is it pre-rendered?
It's fully generative and runs in real time on your GPU. The Bass Tunnel engine performs a live FFT on the audio and drives bass, mid and treble bands separately — kick drums, leads and pads each pull their own motion. No two seconds of output look the same, which is why it doesn't end up looking like a 30-second .webm loop on repeat.
Can I save this exact look as a preset?
Yes. Once you've adjusted colour shift, zoom and iteration depth in the dashboard, click "Save preset". Your preset gets a permanent viewer URL — you can paste the same URL into every stream and the visual will look identical each time. Plus and Pro accounts can save unlimited presets and share them on the marketplace.
Does it work on Mac, Windows and Linux?
Yes. Because Vortexia is a browser-based WebGL engine, it runs anywhere a recent Chrome, Edge or Firefox does — including Mac, Windows, Linux, ChromeOS, and the embedded Chromium that ships with OBS Browser Source.
