Best Multi-Agent Framework for Python

Python is the lingua franca for multi-agent frameworks — every framework Buzzi tracks ships a production-grade Python SDK. Choose by workload, not by language: LangGraph for graph-based control flow, CrewAI for fast role-based prototypes, Pydantic AI for typed minimalism, and AutoGen for emergent adaptive workflows.

Constraint: No constraints — Python supports every tracked framework.

FAQ

  1. Which multi-agent framework is best for Python?

    No constraints — Python supports every tracked framework. The wizard ranks every viable option for your specific workload.

  2. Can I switch frameworks after starting in Python?

    Yes, but the cost is real — most agent code couples to its framework's primitives. Pick once, deliberately.

  3. Does Python performance differ across frameworks?

    Marginally. Token costs dominate runtime; framework-level overhead is a small fraction of total cost in most workloads.

  4. Are the recommendations for Python the same as Python?

    Python sees the full field; recommendations vary by workload, not by language.
