Theatre.js is a JavaScript animation library with a professional motion design toolset, combining a visual sequence/graph editor in the browser with programmatic APIs. It animates any JS variable, making it suitable for THREE.js scenes, React Three Fiber, HTML/SVG, and generative art.

Use cases

  • animate 3d objects in three.js scenes
  • keyframe animation editor for react three fiber
  • design micro-interactions for web ui
  • choreograph generative interactive art
  • animate html and svg elements visually
  • sync web animations with audio
  • fine-tune animation curves with a graph editor

When to choose

  • you need high-fidelity, frame-precise motion graphics on the web
  • you want to blend code-driven and visual keyframe editing workflows
  • you animate THREE.js or React Three Fiber scenes with cameras, lights, and materials
  • you need an extensible animation studio with custom tools

When to avoid

  • you only need simple CSS transitions or basic tweening
  • you need a mature 1.0 release and long-term API stability guarantees
  • your project is not JavaScript/browser-based
  • you require a fully offline design tool without a browser
