OpenUI Standard

OpenUI Standard is an open-source generative UI framework that streams live agent-driven interfaces with fewer tokens.

OpenUI is a full-stack, framework-agnostic generative UI framework built on OpenUI Lang. It lets AI agents stream live charts, forms, cards, tables, and dashboards progressively as models respond. The system renders one response across React, Vue, Svelte, React Native, email, and script tags while keeping user interfaces interactive. It integrates with models like OpenAI, Anthropic, Gemini, DeepSeek, xAI, and Mistral, alongside backends like Vercel AI SDK, LangChain, LangGraph, Convex, and Cloudflare. Developers can bring their own components from libraries like shadcn/ui, Material UI, Ant Design, Radix UI, Chakra UI, and Mantine. The platform ensures safety by composing components without executing arbitrary code.
