AG-UI standardizes how front-end applications connect to AI agents through an open protocol. Think of it as a universal translator for AI-driven systems- no matter what language an agent speaks: AG-UI ensures fluent communication.

​
Why AG-UI?

AG-UI helps developers build next-generation AI workflows that need real-time interactivity, live state streaming and human-in-the-loop collaboration.

AG-UI provides:

  • A straightforward approach to integrating AI agents with the front-end through frameworks such as CopilotKit 🪁
  • Building blocks for an efficient wire protocol for human⚡️agent communication
  • Best practices for chat, streaming state updates, human-in-the-loop and shared state

​
Architecture

At its core, AG-UI bridges AI agents and front-end applications using a lightweight, event-driven protocol:

  • Front-end: The application (chat or any AI-enabled app) that communicates over AG-UI
  • AI Agent A: An agent that the front-end can connect to directly without going through the proxy
  • Secure Proxy: An intermediary proxy that securely routes requests from the front-end to multiple AI agents
  • Agents B and C: Agents managed by the proxy service
