UltimateUI alpha documentation

WebKitGTK · C# · Binary Opcode Bridge

Build native-feeling WebKit apps in C#.

UltimateUI lowers strongly typed C# DOM into binary opcode frames, then a fixed WebKitGTK shim handles mount, update, and event back-channel work.

Read DocsRun Sample
var app = App.Create();
var button = new Button("Click");

app.Mount(root);
app.Update(tx => tx.SetText(button, "Updated"));
