Native engine, web delivery
Counter-Strike 1.6 Powered by WebAssembly
CSJS brings the Xash3D FWGS runtime to the browser instead of imitating it. WebAssembly executes the engine, the canvas renders the game, and a gateway connects web networking to a dedicated server.

A complete browser runtime
Running the engine is only one part of the job. CSJS also adapts files, graphics, networking, and input for the web.
Engine
Compiled with Emscripten
The Xash3D FWGS codebase is built as JavaScript and WebAssembly so modern browsers can execute the game runtime.
Rendering
GLES on canvas
The engine's GLES-compatible renderer draws through the browser canvas while preserving the familiar Counter-Strike 1.6 presentation.
Networking
WebSockets meet UDP
Browser-safe WebSocket traffic passes through a gateway to the UDP protocol used by the dedicated server.
Runtime
Browser-native launch
The client initializes Xash3D inside the browser and coordinates rendering, input, audio, and networking.
What happens when you join
The website hands the selected server to a framework-independent browser client.
- 01
Initialize the client
CSJS prepares the canvas, browser controls, audio, and networking for the selected server.
- 02
Start the engine
The WebAssembly runtime configures the renderer and launches Xash3D FWGS.
- 03
Connect to the server
The client opens a WebSocket to the game gateway, which bridges the browser session to the UDP server.
Questions
Is CSJS a recreation of Counter-Strike 1.6?
No. CSJS compiles the Xash3D FWGS engine for the web with Emscripten and WebAssembly, then connects it to browser-specific storage, input, and networking.
How does a browser connect to a Counter-Strike 1.6 server?
The browser client uses a WebSocket connection. A CSJS gateway translates that traffic for the UDP-based dedicated game server.
