WebKit is a web browser engine used to build the core rendering and layout systems required to display web content. It provides the primary logic necessary to power fully functional web browsers and embedded web views.
The project enables the rendering of web pages by processing HTML and CSS standards. It focuses on cross-platform support for macOS, iOS, and Linux environments, and allows for the integration of web browser windows within native applications.
The engine handles JavaScript execution through optimization and tiered compilation. It manages the visual lifecycle of a page via a tree-based layout engine and a rendering pipeline that converts code into visual layouts. Stability and performance are addressed through a multi-process architecture and hardware-accelerated compositing.
