About adk-go
google/adk-go
An open-source, code-first Go toolkit for building, evaluating, and deploying sophisticated AI agents with flexibility and control.
Provides a modular, multi-agent framework with built-in tool ecosystems and custom function integration, optimized for Go's concurrency model. Model-agnostic architecture works across Gemini and other LLMs, with first-class support for cloud-native deployments like Google Cloud Run. Code-first approach enables agents to be defined, tested, and versioned directly in Go with seamless orchestration of specialized agent workflows.
