adk-java

The Agent Development Kit (ADK) for Java is an open-source, code-first toolkit designed for building, evaluating, and deploying sophisticated AI agents. It enables developers to define agent behavior, orchestration, and tool use directly in Java code for fine-grained control and robust integration with Google Cloud services.

adk-java is currently grouped under Multi-Agent, which makes it easier to evaluate through workflow fit instead of isolated features alone. Based on the available data, it leans most heavily toward Rich Tool Ecosystem for diverse agent capabilities and Google ecosystem integration and Building advanced AI agents with fine-grained control over their behavior and orchestration.. The listed license is Apache-2.0, which is useful when adoption constraints matter. It also shows measurable community traction with 1.7k GitHub stars.
