• A discontinued JavaScript framework that bypassed the browser’s DOM with its own rendering engine, backed by GPU-accelerated CSS3 transforms. It combined a 3D layout engine with a 3D physics animation engine, targeting 60 FPS performance across DOM, Canvas, and WebGL outputs. It gained early traction for enabling native-quality performance in web apps but faded due to SEO and accessibility hurdles from its non-standard render tree, and the rise of React’s virtual DOM approach. Famo.us was first announced in 2013; development effectively ceased by 2017.
