ABOUT
A free, browser-based audio-reactive visual engine built for the way streamers and DJs actually work — in OBS, in a browser tab, with zero install.
Vortexia is a GPU-accelerated audio-reactive visual engine that runs entirely in a regular browser tab. There is nothing to download, nothing to install, no plugin. You pick a visual at vortexia.live/demo and paste a single Browser Source URL into OBS, Streamlabs, Kick, Twitch, YouTube Live, or TikTok Live.
The visuals are generative — not pre-rendered loops — and react in real time to the bass, mid, and treble bands of whatever audio your stream is playing. Every frame is unique.
Vortexia is built and maintained by Yousef, an independent engineer. It is operated as a one-person product — every shader, every preset, every line of OBS-integration code is written and shipped by the same person who answers your support emails.
That means three things: tight feedback loops, no investor-driven feature creep, and a product roadmap that follows what streamers and DJs actually ask for. The blog documents engineering decisions, comparisons against existing VJ tools, and step-by-step setup guides.
