What is Google ADK?

Google Agent Development Kit (ADK) is an open-source Python framework for building, evaluating, and deploying AI agents. It supports multi-agent architectures, tool integration, and first-class compatibility with Gemini models and Google Cloud services.

Our Review

Google ADK is the most natural choice for teams already invested in Google Cloud and Gemini. The eval framework is particularly well-designed — most frameworks treat evaluation as an afterthought, but ADK treats it as a first-class citizen. Expect rapid iteration as Google doubles down on the agentic space.
