← Back to Overview: Agents
What Is Google ADK
Google's Agent Development Kit is a framework for building, deploying, and managing AI agents on Google Cloud. It provides abstractions for agent state, tool integration, session management, and multi-agent orchestration.
When to Use ADK
- You are deploying on Google Cloud / Vertex AI
- You need tight integration with GCP services (BigQuery, Cloud Storage, etc.)
- You want managed agent infrastructure with built-in observability
