If you want a Winamp visualizer online, you almost certainly want MilkDrop, the preset-driven visualizer Ryan Geiss made for Winamp, or AVS, the Advanced Visualization Studio that Winamp also shipped. MilkDrop lives on in the browser: Butterchurn is a free, open-source WebGL implementation that runs the original presets, and Webamp, Winamp 2 rebuilt for the browser, includes it, so the whole classic experience fits in a tab. That is the honest answer if nostalgia is the point. Vortexia is a modern take on the same itch, built for streaming: instead of replaying preset scripts, it draws real fractals on your graphics card every frame, with bass, mids and treble each moving a different part of the picture and a punch on every kick. It adds to OBS as one Browser Source, is controlled from a dashboard while you are live, and reacts to Twitch follows, subs, bits and raids. The free plan runs at 720p with a small watermark.

Frequently asked questions
Can I use MilkDrop online?
Yes. Butterchurn is a free, open-source WebGL implementation of MilkDrop that runs the original presets in a browser, and Webamp, Winamp 2 rebuilt for the browser, has it built in.
Is Vortexia MilkDrop?
No. MilkDrop is a specific preset-driven engine, and its faithful browser version is Butterchurn. Vortexia computes fractals directly instead, so it does not load MilkDrop presets and does not pretend to.
Can I load my old MilkDrop presets?
No. MilkDrop presets are per-pixel equation scripts for its own engine, while Vortexia presets are settings for its fractal shaders. If you have a preset collection you want to keep using, Butterchurn is the right tool.
Does it react to music like MilkDrop did?
Both split the sound into bass, mids and treble: MilkDrop hands those values to each preset’s equations. Vortexia uses them directly, the bass for zoom, speed and glow, the mids for the shape and the treble for colour intensity, and adds a punch on every detected kick.
Then why use Vortexia instead?
For streaming. It adds to OBS or Streamlabs as one Browser Source URL, you control it from a dashboard while you are live, and it reacts to channel events such as subs, bits and raids, which a music-only visualizer cannot know about.
Do I need to install anything?
No. It runs in a browser tab. In Chrome or Edge on Windows, set Listening to Music / system to hear your player directly; otherwise it listens through your microphone, an audio interface or a virtual cable.
