AG-UI: Connect AI Agents to Your App

AG-UI is an open source protocol that connects AI agents to frontends. It streams typed events so your app can show live text, tool calls, and state changes.

AG UI, an open source protocol, turns agent output into live app events. It’s a set of rules that lets your frontend show what an AI agent is doing right now.

You want to build a chat app that streams answers from an AI agent, but every agent framework sends data in its own way, so you end up writing custom glue code for each one.

AG UI is an open source project that fixes this. It defines one event format any agent can speak, and your app just listens. It ships SDKs for TypeScript, Python, and .NET.

In the Dojo demo, you see a chat pane render a generated haiku, a travel planner card, and a recipe form. The agent’s events drive each update live.

So AG UI gives you a shared event stream between agents and your UI. You write the frontend once, and it works with any agent that follows the protocol.
