Google ADK: Ecosystem for Multi-Agent System Development

Google's Agent Development Kit (ADK) facilitates the creation, management, evaluation, and deployment of multi-agent systems, promoting software engineering principles in agent development.
The ADK ecosystem includes integrations with various tools and platforms, such as Zep AI for memory, Heurist AI for standardized agent development, ElevenLabs for voice-enabled agents, FastAPI and Streamlit for multi-agent travel planners, and libraries like LiteLLM for vendor-agnostic LLM integration.
Projects built with ADK demonstrate diverse applications, including AI-powered travel planning, blog post generation from YouTube videos, and comprehensive AI analysis agents for LLM updates and trends, showcasing the ADK's versatility.
According to additional sources, the ADK is model-agnostic and deployment-agnostic, supporting integration with LLMs like Meta Llama and Nemotron-Ultra-253B, and tools like Tavily, Exa, and Firecrawl, enabling the creation of production-grade agent workflows.
The Agent2Agent (A2A) protocol, supported by Microsoft, aims to standardize agent interoperability, independent of framework or vendor, fostering collaboration between agents.
Additional sources highlight community interest in ADK integrations with platforms like Box, Fetch.ai's uAgents, and Airbnb's MCP server, as well as the development of tools for agent workforce accounting, focusing on observability, performance, and fairness of multi-AI agent decisions.
