AG-UI: the Agent-User Interaction Protocol. Bring Agents into Frontend Applications.
Event-based protocol with ~16 standard event types and flexible transport-agnostic middleware that works across SSE, WebSockets, webhooks, and other transports. Supports bi-directional state sync, generative UI, real-time context enrichment, and frontend tool integration. Integrates with 10+ agent frameworks (LangGraph, CrewAI, Pydantic AI, LlamaIndex, AWS Bedrock, Google ADK, Microsoft Agent Framework) and complements MCP and A2A protocols in the agentic stack.
