About each tool
AutoGen
AutoGen, developed by Microsoft Research, is a framework for building applications where multiple AI agents converse with each other (and optionally humans) to solve tasks. It pioneered the concept of conversable agents with customizable behaviors. AutoGen 0.4 introduced an event-driven architecture with better scalability and modularity. It's particularly strong for research applications and complex reasoning tasks requiring multi-turn agent discussions.
CrewAI
CrewAI enables developers to create teams of AI agents that collaborate on complex tasks. Each agent has a defined role, goal, and backstory, and they work together through a structured process — sequential, hierarchical, or consensual. It abstracts away the complexity of multi-agent coordination while providing granular control over delegation, memory, and tool usage. CrewAI has grown rapidly to become one of the top multi-agent frameworks alongside AutoGen and LangGraph.
