When to choose:
  • You want a Python framework that combines autonomous role-based agent teams (Crews) with deterministic event-driven workflows (Flows).
  • You need built-in checkpointing, structured outputs, human-in-the-loop input, and MCP/A2A support under an MIT license.
When to skip:
  • Your stack is .NET or multi-language; Microsoft Agent Framework or Google ADK cover non-Python runtimes.
  • You want a lightweight, single-agent loop focused purely on strict Pydantic type validation; Pydantic AI is simpler for that.
