For a new project I am working on (more to be announced) I was looking for a standalone websocket connection manager. Because still many public and private XMPP servers offer only the TCP transport or BOSH.

There are already existing projects websocket connection managers. But I ran into some issues with them for my current use case. Usually I am not trying to re-invent the wheels ;-)

After WebSocket support came to DotNetty which one of the latest releases, and MatriX vNext of course having full support for XMPP XML streams and clients I was considering creating my own proxy.

So it took only a 90 minute flight to come up with a working solution. I would not consider this solution as production ready yet. But the current design using DotNetty and MatriX vNext can support this at high scale.

When you are interested you can checkout the project on GitHub here:
