AG-UI is an open, lightweight, event-based protocol for agent-human interaction, designed for simplicity & flexibility: During agent executions, agent backends emit events compatible with one of AG-UI's ~16 standard event types Agent backends can accept one of a few simple AG-UI compatible inputs as arguments AG-UI includes a flexible middleware layer that ensures compatibility across diverse environments: Works with any event transport (SSE, WebSockets, webhooks, etc.) Allows for loose event format matching , enabling broad agent and app interoperability It also ships with a reference HTTP implementation and default connector to help teams get started fast. Learn more about the specs → Why AG-UI? AG-UI was developed based on real-world requirements and practical experience building in-app agent interactions. Where does AGUI fit in the agentic protocol stack? AG-UI is complementary to the other 2 top agentic protocols MCP gives agents tools A2A allows agents to communicate with other agents AG-UI brings agents into user-facing applications 🚀 Features 💬 Real-time agentic chat with streaming 🔄 Bi-directional state synchronization 🧩 Generative UI and structured messages 🧠 Real-time context enrichment 🛠️ Frontend tool integration 🧑‍💻 Human-in-the-loop collaboration 🛠 Supported Integrations AG-UI was born from CopilotKit's initial partnership with LangChain and CrewAI - and brings the incredibly popular agent-user-interactivity infrastructure to the wider agentic ecosystem. 1st party = the platforms that have AG‑UI built in and provide documentation for guidance.
