You can do that, no problem. Be careful to not use the actor's mutable state from callbacks running on other threads, though. Perhaps better to start the Netty server outside of the actor. You have to interact with the actor using messages anyway. http://doc.akka.io/docs/akka/2.4.7/general/jmm.html#Actors_and_shared_mutable_state You could look at Akka Http as an alternative: http://doc.akka.io/docs/akka/2.4.7/scala/http/routing-dsl/websocket-support.html > > Second, my Akka application spawns several WebSocket clients to other > services.

Same comment here, be careful to not close over the actor's state.
