# The Servo Book API docs Servo is a web browser engine written in the Rust programming language, and currently developed on 64-bit Linux, 64-bit macOS, 64-bit Windows, and Android. Work is still ongoing to make Servo consumable as a webview library. Currently, the recommended way to run Servo as a browser is via servoshell, our winit and egui-based demo browser. If you'd like to embed Servo in your runtime, or servo-gtk, a GTK4-based web browser widget.
