You can use Ultralight to render HTML and CSS interfaces directly inside video games and native desktop applications. It provides a lightweight WebKit fork designed for low memory consumption and high frame rates. You can manipulate the document object model directly from C or C++ without running a JavaScript virtual machine, or run modern JavaScript frameworks if needed. It features both GPU and multithreaded CPU rendering modes, supports vector graphics, and plays media cutscenes up to 4K resolution across desktop and game console environments.
