autogen vs harness-sdk
AI agent frameworks compared
autogen and harness-sdk both help developers build AI agents and workflows with models and tools. autogen focuses on multi-agent orchestration and is in maintenance mode, while harness-sdk offers ready-made harnesses and lower-level SDKs for Python and TypeScript.
autogen: Build Multi-Agent AI Applications
AutoGen is a Python framework for building AI agents that work independently or alongside people. It supports multi-agent orchestration, model and tool integrations, and prototyping, but is now in maintenance mode.
harness-sdk: Build and Run AI Agents in Python and TypeScript
Strands Agents provides Python and TypeScript tools for building AI agents, from a ready-made harness to a customizable agent SDK. It suits teams that want model flexibility and control over agent execution without a hosted control plane.

Key differences
- autogen provides Core, AgentChat, and Extensions APIs for event-driven systems and multi-agent patterns; harness-sdk pairs assembled harnesses with lower-level SDKs for configuring the agent loop.
- autogen is described as a Python framework, with Python and .NET resources in its ecosystem; harness-sdk provides tools for Python and TypeScript.
- autogen is licensed under CC-BY-4.0, while harness-sdk uses Apache-2.0.
- autogen is in maintenance mode, with contributions limited to bug fixes, security patches, and documentation; harness-sdk is not archived.
- autogen includes AutoGen Studio for prototyping and AutoGen Bench for evaluation; harness-sdk includes a CLI, lifecycle controls, hooks, tracing, and guardrails.
- harness-sdk runs agents in your process without a hosted control plane; autogen supports local or distributed runtimes.
Choose autogen if you…
- maintain or migrate an existing AutoGen application.
- want to prototype multi-agent workflows with AutoGen Studio.
- need its event-driven agents, AgentChat patterns, or distributed runtimes.
Choose harness-sdk if you…
- want a ready-made Python or TypeScript harness, or lower-level SDKs to control the agent loop.
- need configurable provider, tool, memory, session, or context-management options.
- need execution limits, tracing, hooks, or guardrails for agent applications.
