Overview

Google’s open-source, code-first framework for building, debugging, evaluating, and deploying production AI agents across multiple languages.

Details

Agent Development Kit is a Google open-source, code-first framework for end-to-end AI agent development. Official sources describe it as supporting building, debugging, evaluating, deploying, and scaling reliable production agents, including multi-agent systems. The ADK documentation says the toolkit helps developers build, manage, evaluate, and deploy AI-powered agents, with quickstarts for Python, Go, Java, and TypeScript. Google also publishes official GitHub repositories including the Python implementation and a TypeScript implementation for building, deploying, and orchestrating AI agent workflows.

When to Use

Use ADK when you want a Google-backed open-source framework for code-first AI agent development. Use it when your workflow needs lifecycle support for building debugging evaluating and deploying production AI agents. Use it when you are building agent workflows that may include multi-agent systems or orchestration. Use it when quickstarts for Python Go Java or TypeScript are relevant to your team.
