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.

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
