AGNO Agent UI is a React component library optimized for constructing AI Agent chat experiences. It includes prebuilt chat windows, message bubbles, input forms, loading indicators, and error-handling patterns. Developers can leverage real-time streaming of model responses, manage conversation state with custom hooks, and theme components to match their brand. The library integrates with popular agent frameworks such as LangChain, enabling multi-step workflows and plugin support. With responsive design and ARIA compliance, AGNO Agent UI ensures accessible, cross-device interactions, letting teams focus on agent logic rather than UI scaffolding.
