Who it's for
Developers building multi-agent systems who need structured agent-to-agent conversation patterns
AutoGen is an open-source framework by Microsoft for creating multi-agent AI applications that can act autonomously or work alongside humans. It enables developers to build systems where multiple specialised agents collaborate through structured conversations to solve complex tasks. AutoGen supports Python and .NET, and provides patterns for agent-to-agent communication, tool use, and human-in-the-loop workflows. The framework is MIT-licensed and self-hosted — you run it in your own environment. Note: AutoGen is now in maintenance mode with limited updates. Microsoft recommends new projects use the newer Microsoft Agent Framework, though existing AutoGen users can continue with community support.
