How the options differ
Positioning
Pydantic AI's site calls it a "model-agnostic Python framework featuring type safety, structured outputs, validation, and seamless observability" (pydantic.dev). Its repository describes it as "How Python does AI" covering agents, realtime voice, image generation and embeddings (GitHub).
CrewAI's repository describes a "Framework for orchestrating role-playing, autonomous AI agents" (GitHub). Its site frames the product as "The Enterprise Agent Build & Runtime" (crewai.com).
Build surfaces
CrewAI's site lists a no-code visual editor exportable to Python, a code-first API, role-based agents and deterministic agent workflows (crewai.com). The Pydantic AI sources describe a Python framework; a no-code editor is not stated in the cited sources.
Governance and operations
CrewAI's site describes a Control Plane with real-time tracing, RBAC and audit, human-in-the-loop approval gates and runtime hooks for PII redaction (crewai.com).
Pydantic AI's site mentions observability and an open-source Pydantic Evals offering for building datasets and comparing runs when prompts, models or tools change (pydantic.dev).
Models and license
Pydantic AI lists support for OpenAI, Anthropic, Google "and more" (pydantic.dev). CrewAI's site mentions multi-LLM testing for swapping models at runtime (crewai.com). Both GitHub APIs report an MIT license.
