Verdict
AutoGen and LangGraph both excel at multi-agent orchestration but take different architectural approaches. AutoGen uses an event-driven model with strong support for conversational agents and code execution, backed by Microsoft. It supports both Python and .NET, making it more versatile for enterprises with mixed-language stacks. LangGraph uses a graph-based control flow with built-in persistence, making it ideal for stateful workflows and production applications requiring human-in-the-loop interactions. AutoGen has slightly more GitHub stars (38K vs 34K) and offers simpler agent-to-agent chat patterns, while LangGraph provides more explicit control over state transitions and workflow cycles. Choose AutoGen if you need Microsoft integration, .NET support, or are building primarily conversational/research agents with code execution needs. Choose LangGraph if you need persistent state across agent sessions, complex graph-based workflows, or production systems with human oversight checkpoints.
FAQ
Neither is universally better — they serve different needs. AutoGen excels at rapid multi-agent conversation setup with Microsoft backing, while LangGraph provides more control over stateful, production-grade workflows.
