What you can do with Openui

OpenUI is an open, framework-agnostic Generative UI framework that lets models stream structured UI, built around the compact OpenUI Lang and runtimes for React, Vue, Svelte, and Angular.

5 use cases

  • Scaffold a streaming generative UI chat app

    Create a ready-to-run app that streams OpenUI Lang output and renders it as live UI.

    View prompt
    Using the thesysdev/openui repo, scaffold a new app named genui-chat-app in <target folder> by running `npx @openuidev/cli@latest create --name genui-chat-app`. Report the start command the CLI prints and confirm that a test prompt in the running app produces streamed UI rather than plain text.

  • Add streamed OpenUI rendering to a React app

    Install the React runtime and prebuilt chat UI to render model output in an existing app.

    View prompt
    In the thesysdev/openui repo, use the @openuidev/react-lang and @openuidev/react-ui packages to add a streamed chat panel to the React project at <target project path>. Expected output is a running chat view that renders OpenUI Lang output; verify by sending one test prompt and confirming a component renders rather than raw text.

  • Generate model prompts from a component list on the server

    Use the framework-agnostic core to build system prompts on a backend or Edge function.

    View prompt
    Using the thesysdev/openui repo, add @openuidev/lang-core to the backend at <target backend path> and generate a system prompt from a component library that has at least two components. Expected output is the prompt text; verify that it lists only the components you defined.

  • Stream a LangChain agent's output as live UI

    Connect a LangChain or LangGraph agent to OpenUI through AG-UI for streamed UI responses.

    View prompt
    In the thesysdev/openui repo, wire the @openuidev/langchain transformer into the LangGraph agent at <target agent path> so its output streams as OpenUI Lang over AG-UI. Expected output is a streamed UI response in the client; verify by running one request that returns a table or form component.

  • Render streamed OpenUI in a Vue, Svelte, or Angular app

    Install the matching runtime to render OpenUI Lang output in a non-React front end.

    View prompt
    Using the thesysdev/openui repo, install the matching runtime for the project at <target project path> (vue-lang, svelte-lang, or angular-lang) and render one streamed OpenUI Lang response. Expected output is a visible model-generated component; verify that it appears progressively rather than all at once.

How to use Openui

  1. Check you have what it needs: Node.js with npm and npx, since the README install and scaffold commands use them; An LLM provider you can call from your backend, because OpenUI sends a generated system prompt to your model; A component library to use or define; the README provides built-in libraries in @openuidev/react-ui.
  2. Open thesysdev/openui on GitHub and read the README and license.
  3. Open a terminal in the folder where you want the project.
  4. Run npx @openuidev/cli@latest create --name genui-chat-app
  5. Change into the new genui-chat-app folder and follow the install and start steps the CLI prints.
  6. Open the app and send a prompt to confirm UI renders as the response streams.

These steps come from our top use case, Scaffold a streaming generative UI chat app, which also has a copy-paste agent prompt.
