I think you are referring to Compose[1].
We differ with/from the alternatives in a number of ways:
- We have No rate limits. We do not limit the number of messages you can queue, the number of queues or any other artificial else.
- All our plans are on dedicated server. We do not setup shared RabbitMQ servers(vhosts).
- We do support HiPE (High performance Erlang).
We have a comparison page[2] where we list more of these differences.
