Agent2Agent (A2A) is an open protocol enabling communication and interoperability between opaque agentic applications.
The Agent2Agent (A2A) protocol helps AI application developers integrate different generative AI agents, built by various companies, to work together seamlessly. It allows these 'opaque' agents to discover each other's capabilities and collaborate on complex tasks, fostering a more interconnected AI ecosystem. This is for developers building multi-agent systems.
22,488 stars. Actively maintained with 16 commits in the last 30 days.
Use this if you are a developer looking to build complex AI applications by orchestrating multiple, specialized generative AI agents from different frameworks and providers.
Not ideal if you are an end-user looking for a ready-to-use AI application, as this is a protocol for developers to build such systems.
