Famo.us is a JavaScript rendering and physics engine for creating web applications with high-performance 3D user interfaces.

Famo.us features a rendering engine that avoids slow DOM-layout and repaint calculations. Instead, it leverages the GPU using CSS3 transform.

Famo.us provides a JavaScript framework designed to build rich, interactive web applications. Famo.us takes an opinionated approach to web development, maintaining a tight control of rendering to achieve performance. The framework also maintains strict modularity for flexibility. Paired with server-side technology designed to match Famo.us on the front end, you can finally create high quality applications that were once reserved only for native development.

For more information see project website Famous.org

The prior version (v.0.3.5) site can be found at deprecated.famous.org
