I have just tried Node RED. When we had IBM people come to show their SaaS offerings they used it as a demo tool, I thought that was quite neat and you could see how their services fit together.

An other tool with a similar interface is Autopilot (https://autopilothq.com/, not affiliated). That one let marketing/product people tune email campaigns themselves where they otherwise would have had to ask developers for help. User events from our product were forwarded to Autopilot and marketing/product could create triggers and quite advanced user journeys (like the onboarding flow) from the event stream without coding.
