Add a Sci-Fi HUD to Your Stream — Chromakey-ready futuristic overlay. Vortexia renders this look — add a sci-fi hud to your stream — using the Chaos Prime engine, which produces beat-locked tunnels and pulses that snap to kick-drum onsets. Because everything runs through WebGL in your browser, there is no plugin to install and nothing to crash your broadcast software. You paste the viewer URL into OBS, Streamlabs and any other broadcasting software as a Browser Source and the visual is live; it reacts in real time to whatever audio your stream is already playing. Free tier runs 720p watermarked; Plus is $49.99/year for 1080p/60; Pro is $119.99/year for 4K/60 with custom shader uploads and priority support. From the dashboard you can adjust colour shift, zoom and iteration depth, save the result as a preset, and the same viewer URL will reproduce the look identically every time.
How to use Add a Sci-Fi HUD to Your Stream
Customize the visual. Open the Vortexia dashboard, choose the Add a Sci-Fi HUD to Your Stream 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 Add a Sci-Fi HUD to Your Stream 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 Chaos Prime 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.
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.
