Agent Development Kit

An open-source AI agent framework integrated with Gemini and Google

What is Agent Development Kit?

Agent Development Kit (ADK) is a flexible and modular framework for developing and deploying AI agents. ADK can be used with popular LLMs and open-source generative AI tools and is designed with a focus on tight integration with the Google ecosystem and Gemini models. ADK makes it easy to get started with simple agents powered by Gemini models and Google AI tools while providing the control and structure needed for more complex agent architectures and orchestration.

Get started:
pip install google-adk

  • Flexible Orchestration

    Define workflows using workflow agents (Sequential, Parallel, Loop) for predictable pipelines, or leverage LLM-driven dynamic routing (LlmAgent transfer) for adaptive behavior.

    Learn about agents

  • Multi-Agent Architecture

    Build modular and scalable applications by composing multiple specialized agents in a hierarchy. Enable complex coordination and delegation.

    Explore multi-agent systems

  • Rich Tool Ecosystem

    Equip agents with diverse capabilities: use pre-built tools (Search, Code Exec), create custom functions, integrate 3rd-party libraries (LangChain, CrewAI), or even use other agents as tools.

    Browse tools

  • Deployment Ready

    Containerize and deploy your agents anywhere – run locally, scale with Vertex AI Agent Engine, or integrate into custom infrastructure using Cloud Run or Docker.

    Deploy agents

  • Built-in Evaluation

    Systematically assess agent performance by evaluating both the final response quality and the step-by-step execution trajectory against predefined test cases.

    Evaluate agents

  • Building Responsible Agents

    Learn how to building powerful and trustworthy agents by implementing responsible AI patterns and best practices into your agent's design.
