CrewAI vs Google Agent Development Kit (ADK)
A side-by-side comparison of capabilities, autonomy, integrations, and pricing to help you choose.
Short answer: choose CrewAI if you want open-source framework for orchestrating role-based, collaborating multi-agent teams (Supervised agent, freemium); choose Google Agent Development Kit (ADK) if you want open-source framework for building and orchestrating multi-agent systems (Supervised agent, free).

CrewAI
- +Clean, lean abstraction (Crews + Flows) that many developers find simpler and faster than heavier frameworks
- +Standalone (no LangChain dependency) with strong multi-agent collaboration primitives out of the box
- +Provides a managed enterprise control plane (observability, RBAC, human-in-the-loop) for moving to production
- -Multi-agent designs can compound error rates and cost; not always cheaper or more reliable than a single agent
- -Newer and smaller ecosystem than LangChain, with fewer integrations and less battle-testing
Google Agent Development Kit (ADK)
- +Backed by Google with first-class deployment to Vertex AI and Cloud Run
- +Built around the open A2A protocol for cross-framework agent interoperability
- +Model-agnostic via LiteLLM despite Gemini-first defaults
- -A framework, not a product: you build, host, and secure agents yourself
- -Strongest when paired with Google Cloud, which can imply lock-in
Which should you choose?
CrewAI is open-source framework for orchestrating role-based, collaborating multi-agent teams, best for developers, enterprise, mid-market. Google Agent Development Kit (ADK) is open-source framework for building and orchestrating multi-agent systems, best for developers, enterprise. The right choice depends on the autonomy level you want, your existing integrations, and your budget, all compared above.
