AG-UI: The Agent-User Interaction Protocol AG-UI is an open, lightweight, event-based protocol that standardizes how AI agents connect to user-facing applications. Built for simplicity and flexibility, it enables seamless integration between AI agents, real time user context, and user interfaces. --- Join our Discord →     Read the Docs →     Go to the AG-UI Dojo →     Follow us → 🚀 Getting Started Create a new AG-UI application in seconds: Useful Links: • The AG-UI Dojo • Build AG-UI-powered applications(Quickstart) • Build new AG-UI framework integrations (Quickstart) • Book a call to discuss an AG-UI integration with a new framework • Join the Discord Community What is AG-UI? 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.

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 LangGraph 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.
