OneSignal prioritizes customer engagement campaigns and marketing automation over low-latency data streaming infrastructure. While it offers push notifications similar to Ably, it lacks the pub/sub messaging backbone, MQTT support, and developer-first APIs essential for building realtime collaborative applications. Teams seeking messaging infrastructure will find OneSignal operates at entirely the wrong layer of the stack.
