**Production teams should evaluate the latest stable release documented by each active project, record the exact package version, and pin it rather than relying on an unbounded latest tag.** The entries below are an October 2026 snapshot; AutoGen's final listed release is retained only for teams maintaining an existing system during migration.

[LangGraph is the better fit](https://docs.langchain.com/oss/python/langgraph/overview) when a Python team needs custom graph state and runtime behavior. [OpenAI Agents SDK is a strong fit](https://openai.github.io/openai-agents-python/) when a lightweight code-first SDK is enough. [CrewAI is clearer](https://docs.crewai.com/en/introduction) for role-based agent teams. [Microsoft Agent Framework is the current Microsoft choice](https://learn.microsoft.com/en-us/agent-framework/overview/). [n8n is strongest](https://docs.n8n.io/) when the central problem is SaaS automation and integration breadth rather than agent-native orchestration.
