Google ADK for Go

Google ADK for Go is an open-source Go toolkit for building, evaluating, and deploying AI agent workflows using software development principles.

The Agent Development Kit for Go provides a modular framework for creating, testing, and deploying AI agent applications. Developers use this toolkit to manage agent workflows, ranging from simple tasks to complex systems, using idiomatic Go code. The framework remains model-agnostic and deployment-agnostic, though it includes optimizations for Google Gemini. It allows for the composition of multi-agent systems and the integration of custom functions or pre-built tools. This toolkit serves developers building cloud-native applications who prioritize concurrency and performance. It emphasizes code-first development to support versioning and testability throughout the agent lifecycle.
