# Web Export in Godot 4.3+

Ship a Godot 4.x game as HTML5/WebAssembly. This covers what is different from a desktop export: the renderer, threading and server headers, browser interop, persistence, and the input and audio rules browsers enforce. All examples target Godot 4.3+ with no deprecated APIs.

**C# projects cannot export to Web in Godot 4** — the .NET editor refuses the export (still true in 4.7.2). The code in this skill is GDScript only for that reason; a C# game that needs a browser build must be ported to GDScript or stay on Godot 3.

> **Related skills:** **export-pipeline** for presets, CLI export and CI/CD, **web-services** for HTTP and WebSockets from the browser, **rendering-pipeline** for what the Compatibility renderer can and cannot do, **audio-system** for buses and playback, **save-load** for save formats.
