The VJ Software You Can Run Anywhere — Professional visuals, zero cost. Vortexia is a free, browser-based alternative to Resolume Arena for streamers and DJs who need audio-reactive visuals without installing anything. The Quantum Web engine produces kaleidoscopic sacred-geometry patterns synced to mid and treble bands entirely on your GPU through WebGL, exposes a viewer URL you paste into OBS, Streamlabs and any other broadcasting software as a Browser Source, and reacts in real time to the audio your stream is already playing. There is no .dll to install, no licence to renew, and nothing to crash your broadcast software. Free tier runs 720p watermarked, Plus is $49.99/year for 1080p/60 and Pro is $119.99/year for 4K/60 with custom shader uploads. Because the visuals are generative rather than pre-rendered loops, the output is unique on every play — which removes the “same five .webm files” problem that makes Resolume Arena libraries feel stale.
How to use The VJ Software You Can Run Anywhere
Customize the visual. Open the Vortexia dashboard, choose the The VJ Software You Can Run Anywhere 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 The VJ Software You Can Run Anywhere 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 Quantum Web 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.
How is this different from Resolume Arena?
Resolume Arena is a desktop application that needs installation, a licence and (in most cases) a separate audio-routing setup. Vortexia runs in a browser tab, ships as a Browser Source URL, and is free to start. The trade-off: Resolume Arena gives you deeper timeline-style sequencing for live shows; Vortexia gives you instant generative output that's easier to deploy on streams and at smaller events.
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.
