AG-UI Protocol: Inside TanStack AI's New Protocol

What is AG-UI and why is everyone talking about it?

In this video, we break down the AG-UI protocol an open-source, lightweight, event-driven standard that sits between your AI agent framework and your application UI. The big idea: agents and providers can emit the same standardized events, so you can swap integrations in/out without breaking changes.

We walk through:
- What AG-UI is and why it matters for standardization
- How standardized events (text, tool calls, lifecycle, state, etc.) make UIs predictable
- A live look at the AG-UI interactive dojo: using the same prompt across different integrations and seeing the same event-style responses
- Key architecture ideas: bidirectional communication + transport-agnostic (WebSockets, SSE, etc.)

If you’re overwhelmed by the growing number of agent frameworks, AG-UI aims to make the protocol layer something you don’t have to think about.
