Microsoft AutoGen vs harness-sdk
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.; harness-sdk: This monorepo holds the Strands Agents SDKs for Python and TypeScript plus Strands harness, a fully assembled agent created with one create_harness() call. It runs in your own process and covers the agent loop, tools, MCP, multi-agent patterns, memory, sessions, guardrails, tracing and evals across Bedrock, Anthropic, OpenAI, Gemini and other providers.
TL;DR
- You maintain an existing AutoGen v0.2 or v0.4 system, or want to run research artefacts built on it such as Magentic-One and AutoGen Bench.
- You want to reference its layered event-driven architecture while planning a migration to Microsoft Agent Framework.
- You are starting a brand-new project; Microsoft states AutoGen is in maintenance mode with no new features and recommends Microsoft Agent Framework.
- You expect AutoGen Studio to be a turnkey production web app (the README notes Studio is for prototyping only).
