Google Agent Development Kit

Google Agent Development Kit (ADK) is an open-source framework for building, debugging, evaluating, and deploying production AI agents. It is model- and deployment-agnostic while offering especially deep integration with Gemini and Vertex AI.

Key features

• Code-first agent development in Python, TypeScript, Java, Go, and Kotlin
• Native support for multi-agent systems and agent-to-agent collaboration
• Built-in local web UI and CLI for debugging
• Tool use, streaming, sessions, memory, and evaluation
• Deployment paths for local environments and Google Cloud

ADK is based on the framework Google uses for agents in its own products and is a major choice for teams building in the Google Cloud ecosystem.
