Agent Development Kit

Agentic AI

Value Proposition & Features

Agent Development Kit (ADK) is Google’s open-source developer framework for building AI agents. It is positioned for agents that can run locally, on hosted services, and on Android mobile devices, and Google’s Android docs describe it as a way to build and integrate sophisticated AI agents directly into Android apps. [q6h5tt] [5z6hq4]
Core features include multi-agent and tool-using agent development, Android support, and deployment-oriented workflows through Google Cloud’s Agent Platform and Agents CLI. [05lmxf] [q6h5tt] Google’s docs also show evaluation and deployment steps as part of the workflow, including deployment to Cloud Run. [05lmxf]
  • Open-source agent framework. [q6h5tt] [5z6hq4]

History and Origin Story

ADK appears to have originated at Google as an open-source agent framework, with later expansion into Android and Kotlin variants. [q6h5tt] [5z6hq4] The public record in the returned sources shows platformization through Google Cloud’s Agent Platform and Agents CLI, suggesting the project has evolved from a framework into part of a broader Google agent-development stack.

Competitive Landscape

Who it's for, who it's not for

ADK is for developers building AI agents who want an open-source framework with Google Cloud and Android integration, plus a workflow for evaluation and deployment. [05lmxf] [q6h5tt] It is especially relevant for teams already using Google Cloud or targeting Android apps. [q6h5tt]
It is not a fit for teams looking for a turnkey no-code agent builder or a non-Google, vendor-neutral enterprise platform. [05lmxf] [q6h5tt] It is also less relevant for users who do not want to work with developer tooling such as CLI-based setup and Python/package workflows. [05lmxf]
