15/100
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.
Adoption RiskExpected friction, training effort, and behavior change needed to move teams onto the alternative.
