Google's own AI agent kit is free. Here's how it works (ADK)

Google's Agent Development Kit (ADK) is a free, open-source framework that enables developers to build AI agents. The ADK provides built-in tools, integrations, and patterns that Google uses internally for its own agent development. It simplifies agent creation by handling common tasks like tool orchestration, state management, and multi-step reasoning workflows.
