What each one is
Google ADK
ADK is Google's code-first framework for building, evaluating and deploying agents: hierarchical multi-agent systems, workflow control, built-in eval and a path to Vertex AI.
- Model-agnostic but optimized for Gemini
- Workflow agents give deterministic orchestration
- Built-in evaluation and deployment story
OpenAI Swarm
Swarm is a deliberately tiny framework showing how agents can hand off work to one another, built for learning rather than production.
- Extremely small and readable
- Clear handoff and routine patterns
- Great teaching material
