Microsoft AutoGen vs metaharness

Microsoft AutoGen: AutoGen is a versatile framework for developing multi-agent AI applications that can operate autonomously or in collaboration with humans. It offers a layered, extensible design, including Core and AgentChat APIs, along with developer tools like AutoGen Studio for no-code GUI development and AutoGen Bench for performance evaluation.; metaharness: MetaHarness is a CLI and browser Studio that mints custom AI agent harnesses from any GitHub repository, creating a repo-aware CLI, coding agent, and local MCP server tailored to the project. It acts as a factory for agent frameworks, allowing users to ship their own branded, npm-publishable AI agents with custom memory, governance, and model routing.
