Moderate Setup (1-3 hours)

You can use Ultralight to embed modern HTML interfaces in games and native applications across multiple platforms including Windows, macOS, Linux, PlayStation, and Xbox. It provides both GPU and CPU rendering options, with the GPU renderer offering maximum performance by integrating directly with your existing rendering pipeline. The library is built on a lightweight WebKit fork and uses significantly less memory than alternatives like Chromium. You can create transparent web overlays, integrate JavaScript with native code, and load custom assets through its API system.
