Building front-end Agentic apps just got 10x easier (open-source)!

If you're building apps where Agents are part of the interface, not just running in the background, AG-UI protocol has become the standard.

For context:
- MCP connects agents to tools
- A2A connects agents to other agents
- AG-UI connects agents to users

It defines a common interface between Agents and the UI layer.

AG-UI itself is Agent framework agnostic, and it lets you:
- stream token-level updates
- show tool progress in real time
- share mutable state
- and pause for human input

The visual below summarizes the latest updates:

- Spin up a full-stack AG-UI app directly from CLI.
- Visualize A2A interactions, and allow them to reach out to the user.
- A fully revamped contributor flow for developers.
- Pydantic AI is now AG-UI compatible.
- Build AG-UI frontends 10x faster with a plug-and-play interface.

Build your own AG-UI client: npx create-ag-ui-app my-agent-app.
