What each one is
AutoGen
AutoGen — the official full name, short for “Automated Generation” — is Microsoft’s open-source framework for building multi-agent AI systems where agents converse to solve tasks, with strong support for code execution and tool use.
- Flexible multi-agent conversation patterns
- Strong code-execution and tool-use support
- Backed by Microsoft Research
Agent Zero
Agent Zero is a fully transparent personal agent framework: it writes and executes code in its own Linux environment, spawns sub-agents, and every behavior is a prompt you can change.
- Everything is a prompt — completely customizable
- Executes real code in an isolated environment
- Hierarchical sub-agents keep context clean
