We have been using WAMP 2 and crossbar in production for a while now. We have js, PHP and python all talking to each other without any issues. We will probably add Go in the next months (prototypes are already working). For authorization and authentication you have to spend some effort to get something working without hardcoded config. Biggest down side is that clustering of the open source router crossbar is not really possible and we haven’t seen any production ready alternatives. Until now this wasn’t really an issue, but it looks like this might be the reason why we will leave WAMP / crossbar this year. Best options to replace this with is probably some solution based on GRPC or NATS.
