Don’t ship another chat UI. Build real AI with AG-UI

Developers often find themselves dealing with complex setups when building AI features, moving from simple API calls to managing multi-step workflows and custom logic. The Agent User Interaction (AG UI) Protocol offers a structured, event-driven approach, allowing developers to construct more sophisticated AI applications beyond basic chat interfaces by standardizing interactions between agents, tools, and user interfaces. Instead of manually handling streams, tools, and UI states, AG-UI provides a protocol layer that facilitates real-time streaming and structured events, enabling developers to write agent logic once and reuse it across different platforms. This guide walks through creating a command-line interface (CLI) client using the AG-UI TypeScript SDK, showcasing how to build an AI experience with streaming output, tool calls, and multi-step interactions. The event-driven model of AG-UI allows responsive UI updates without complex state management and can be particularly beneficial for applications requiring multiple clients or persistent memory. Through practical examples, such as integrating a weather tool, the guide illustrates the ease of handling complex tasks and event flows, highlighting AG-UI’s potential in production AI features while recognizing its limitations for simpler use cases.
