I am afraid http-kit is much feature less than SignalR. SignalR provides client side javascript[1], and hubs. http-kit provide non of these. http-kit just provide a way to get a Channel that can be used to push data to client, The Channel can be WebSocket or HTTP (long polling/streaming). IMO, http-kit is more like a unix command line tool, tiny and focus.
Socket.IO[2] is more like SignalR compare to http-kit.
