An agent run dies halfway through. You restart it. The customer receives a second onboarding email.
Nothing in that sentence is a framework bug. AutoGen, CrewAI, LangGraph, and Flowise will all let it happen, because none of them can reach into your mail provider and pull the message back. Durable execution restores orchestration state. It does not make an external payment, email, or ticket API transactional.
That gap is missing from almost every "best agent framework" comparison, and it is the gap that decides whether your system survives contact with production.
The comparison is a category error to begin with
AutoGen, CrewAI, and LangGraph are code-side orchestration frameworks. Flowise is a visual builder and runtime platform spanning Assistant, Chatflow, and Agentflow. Putting all four in one ranked list is convenient and wrong — they are not four skins over the same runtime.
