This extension provide a WebSocket like API to build multiplayer game on the web (and hardware). It’s still very much a work in progress. **Read below, it will not work as is in the editor**.

- demo [https://pelikhan.github.io/pxt-sockets/](https://pelikhan.github.io/pxt-sockets/)
- github [https://github.com/pelikhan/pxt-sockets](https://github.com/pelikhan/pxt-sockets)

The simulation support is rather clunky right now because it can’t be tested in game yet. However if you copy custom.js/loader.js into your generate repo, you’ll be able to talk to WSS.
