Google Agent Development Kit (ADK) is an open-source Python framework for building, composing, and deploying multi-agent AI systems. It handles the hard parts of agent orchestration — tool use, memory, inter-agent communication, and deployment — with first-class support for Gemini models and Google Cloud, but designed to be model-agnostic. The framework reached 8,200+ GitHub stars within weeks of launch, making it one of the fastest-growing agent infra repos this spring. ADK ships with built-in support for common agent patterns (sequential, parallel, coordinator-worker), a robust tool abstraction layer, and native MCP support. It integrates cleanly with Google's broader AI stack (Vertex AI, Cloud Run) but also works standalone with other model providers. ADK enters a crowded field — LangGraph, CrewAI, and AutoGen all offer overlapping functionality — but Google's official backing, deep Gemini integration, and the framework's quality-of-life improvements (particularly around deployment and state management) have made it an instant reference implementation for many teams.

Reviewer scorecard
“The API design is clean and the documentation is genuinely good — rarer than it should be for a framework launch. The built-in agent patterns cover 80% of multi-agent use cases out of the box, and the MCP support means you're not locked into Google's tool ecosystem.”
“Google has a long history of abandoning developer-facing products. Building your agent infrastructure on ADK means betting Google doesn't sunset it in 18 months. LangGraph and CrewAI have more stable governance and active independent communities.”
“ADK represents the formalization of multi-agent orchestration as a first-class engineering discipline. Google putting their weight behind a standard framework accelerates the entire ecosystem, regardless of whether ADK specifically wins.”
“Vendor lock-in concerns. Hard to migrate once you're committed.”
“This is solidly a developer tool with no real surface for non-technical users. As infrastructure it's impressive, but until it's wrapped in products with accessible interfaces, it's not something creators will interact with directly.”
“The API design is thoughtful. Integrates well with existing stacks.”
