Agent Development Kit

The Agent Development Kit (ADK) is an open-source, code-first framework for building and orchestrating complex, production-ready AI agent systems.

ADK (Agent Development Kit) provides a flexible, code-first foundation for developing and deploying sophisticated AI agents. The framework is model-agnostic (supports Gemini, Anthropic, etc.) and deployment-agnostic, though optimized for Vertex AI Agent Engine. Developers gain precise control over agent behavior and orchestration: use **LLM Agents** for dynamic reasoning or **Workflow Agents** (Sequential, Parallel) for predictable pipelines. ADK simplifies multi-agent architecture and tool integration, supporting pre-built tools (Search), custom functions, and third-party libraries. It includes a built-in Dev UI for rapid local debugging, ensuring a streamlined software development lifecycle for your agentic applications.
