Butterchurn is a WebGL2-based JavaScript library that reimplements the MilkDrop music visualizer in the browser. It renders audio-reactive visual presets using the Web Audio API and ships with a companion preset package.
Use cases
- visualize music in the browser with WebGL
- add audio-reactive visuals to a web music player
- render MilkDrop presets on a website
- visualize microphone input live
- add a music visualizer to a streaming or karaoke app
- detect WebGL2 support before loading a visualizer
When to choose
- You need a browser-based MilkDrop-compatible music visualizer
- You want audio-reactive visuals driven by Web Audio API nodes
- You want to load and blend classic MilkDrop presets
When to avoid
- You need server-side or native desktop visualization
- Your target browsers lack WebGL 2 support
- You need a lightweight static visualizer without audio analysis
