ADK (Agent Development Kit)
Overview
Open-source framework for building, running, evaluating, and deploying multi-agent systems.
ADK (Agent Development Kit) is an open-source agent development framework for building production-oriented multi-agent systems. It supports multiple SDK languages, agent workflows, tool and model integrations, runtime options, observability, evaluation, and deployment paths for teams building custom agent applications.

What the evidence says about ADK (Agent Development Kit)
ADK is a developer framework rather than a finished assistant: it gives engineering teams SDKs, workflow primitives, runtime options, integrations, evaluation, observability, and deployment guidance for building custom multi-agent systems.

Verified capabilities
- Open-source agent framework
The official page describes ADK as an open-source agent development framework for building, debugging, and deploying reliable AI agents at enterprise scale.[1]
- Multi-language SDK support
ADK is presented with support for Python, TypeScript or JavaScript, Go, Java, and Kotlin, with code snippets and references for those ecosystems.[1]
- Graph and multi-agent workflows
The official page highlights ADK TypeScript 2.0 GA with graph workflow support and lists workflow features including graph routes, data handling, human input, dynamic workflows, collaborative workflows, sequential workflows, loop workflows, parallel workflows, custom template workflows, and agent routing.[1]
- Model and tool integrations
The official navigation lists model support and integrations including Gemini, Gemma, Claude, OpenAI, Ollama, vLLM, LiteLLM, LiteRT-LM, Google Search grounding, MCP tools, OpenAPI tools, Apigee AI Gateway, and model routing.[1]
- Agent runtime and execution interfaces
ADK includes run-time oriented documentation for Agent Runtime, web interface, visual builder, command line, API server, ambient agents, resuming agent runs, canceling agent runs, runtime configuration, and event loop behavior.[1]
- Deployment guidance
The official page lists deployment topics including Agent Runtime, standard deployment, agents-cli, testing deployed agents, Cloud Run, and GKE.[1]
- Observability and evaluation
ADK documentation sections cover observability features such as logging, metrics, and traces, as well as evaluation topics including criteria, user simulation, environment simulation, custom metrics, optimization, and safety and security.[1]
- Agent communication protocols
The official page includes MCP and A2A Protocol documentation, including A2A quickstarts for exposing and consuming agents across Python, Go, Java, and Kotlin.[1]
Where it fits best
- Engineering teams building custom multi-agent systems that need to move beyond prototypes into debugging, deployment, evaluation, and observability workflows.[1]
- Developers who want SDK coverage across Python, TypeScript or JavaScript, Go, Java, and Kotlin.[1]
- Agent applications that need workflow patterns such as graph workflows, collaborative workflows, sequential workflows, loop workflows, parallel workflows, custom template workflows, and routing.[1]
Buying and deployment notes
The ADK framework/software is described as open-source and licensed with permission granted free of charge. No paid ADK plan is shown in the supplied official context.[1]
Platforms: Python, TypeScript, JavaScript, Go, Java, Kotlin[1]
Deployment: Local development with CLI, Web interface, API server, Agent Runtime, Standard deployment, Cloud Run, GKE[1]
Important considerations
- ADK is a development framework, so adoption requires building and configuring agents with code, tools, runtimes, and deployment choices rather than purchasing a ready-made task-specific agent.[1]
- The supplied official context identifies SDK and documentation coverage for Python, TypeScript or JavaScript, Go, Java, and Kotlin; other language ecosystems are not shown in the supplied context.[1]
- The supplied context verifies that the ADK software is free and open-source, but it does not provide pricing details for any external models, cloud infrastructure, or third-party services used with agents built on ADK.[1]
