Verdict: Choose Google ADK if you're building agents on Google Cloud or Vertex AI, or need multimodal agents. Builders in our cited sources recommend it for those cases, and the kit is free and open source under Apache-2.0. The trade-off is a younger community than LangGraph or CrewAI, so you'll find fewer examples and answers. If you aren't tied to Google's platform, LangGraph has the larger production community.
Based on cited builder feedback and official docs/pricing. Not a hands-on test.
