Tambo is a React toolkit for building agents that render UI (also known as generative UI). Register your components with Zod schemas. The agent picks the right one and streams the props so users can interact with them. "Show me sales by region" renders your ``. "Add a task" updates your ``. **[Get started in 5 minutes →](#get-started)** https://github.com/user-attachments/assets/8381d607-b878-4823-8b24-ecb8053bef23 ### What's Included Tambo is a fullstack solution for adding generative UI to your app. You get a React SDK plus a backend that handles conversation state and agent execution. **1. Agent included** — Tambo runs the LLM conversation loop for you. Bring your own API key (OpenAI, Anthropic, Gemini, Mistral, or any OpenAI-compatible provider). Works with agent frameworks like LangChain and Mastra, but they're not required. **2. Streaming infrastructure** — Props stream to your components as the LLM generates them. Cancellation, error recovery, and reconnection are handled for you. **3. Tambo Cloud or self-host** — Cloud is a hosted backend that manages conversation state and agent orchestration. Self-hosted runs the same backend on your infrastructure via Docker. Most software is built around a one-size-fits-all mental model. We built Tambo to help developers build software that adapts to users. ## Get Started ```bash npm create tambo-app my-tambo-app # auto-initializes git + tambo setup cd my-tambo-app npm run dev ``` [**Tambo Cloud**](https://tambo.link/yXkF0hQ) is a hosted backend, free to get started with plenty of credits to start building. **Self-hosted** runs on your own infrastructure.

Zod schemas define the props. These schemas become LLM tool definitions—the agent calls them like functions and Tambo renders the result. ### Generative Components Render once in response to a message. Charts, summaries, data visualizations. https://github.com/user-attachments/assets/3bd340e7-e226-4151-ae40-aab9b3660d8b ```tsx const components: TamboComponent[] = [ { name: "Graph", description: "Displays data as charts using Recharts library", component: Graph, propsSchema: z.object({ data: z.array(z.object({ name: z.string(), value: z.number() })), type: z.enum(["line", "bar", "pie"]), }), }, ]; ``` ### Interactable Components Persist and update as users refine requests. Shopping carts, spreadsheets, task boards. https://github.com/user-attachments/assets/12d957cd-97f1-488e-911f-0ff900ef4062 ```tsx const InteractableNote = withInteractable(Note, { componentName: "Note", description: "A note supporting title, content, and color modifications", propsSchema: z.object({ title: z.string(), content: z.string(), color: z.enum(["white", "yellow", "blue", "green"]).optional(), }), }); ``` Docs: [generative components](https://docs.tambo.co/concepts/generative-interfaces/generative-components), [interactable components](https://docs.tambo.co/concepts/generative-interfaces/interactable-components) ### The Provider Wrap your app with `TamboProvider`. You must provide either `userKey` or `userToken` to identify the thread owner. ```tsx ``` Use `userKey` for server-side or trusted environments. Use `userToken` (OAuth access token) for client-side apps where the token contains the user identity. See [User Authentication](https://docs.tambo.co/concepts/user-authentication) for details. Docs: [provider options](https://docs.tambo.co/reference/react-sdk/providers) ### Hooks `useTambo()` is the primary hook — it gives you messages, streaming state, and thread management. `useTamboThreadInput()` handles user input and message submission. ```tsx const { messages, isStreaming } = useTambo(); const { value, setValue, submit, isPending } = useTamboThreadInput(); ``` Docs: [threads and messages](https://docs.tambo.co/concepts/conversation-storage), [streaming status](https://docs.tambo.co/concepts/generative-interfaces/component-state), [full tutorial](https://docs.tambo.co/getting-started/quickstart) ## Features ### MCP Integrations Connect to Linear, Slack, databases, or your own MCP servers. Tambo supports the full MCP protocol: tools, prompts, elicitations, and sampling. ```tsx import { MCPTransport } from "@tambo-ai/react/mcp"; const mcpServers = [ { name: "filesystem", url: "http://localhost:8261/mcp", transport: MCPTransport.HTTP, }, ]; ; ``` https://github.com/user-attachments/assets/c7a13915-8fed-4758-be1b-30a60fad0cda Docs: [MCP integration](https://docs.tambo.co/concepts/model-context-protocol) ### Local Tools Sometimes you need functions that run in the browser. DOM manipulation, authenticated fetches, accessing React state. Define them as tools and the AI can call them. ```tsx const tools: TamboTool[] = [ { name: "getWeather", description: "Fetches weather for a location", tool: async (params: { location: string }) => fetch(`/api/weather?q=${encodeURIComponent(params.location)}`).then((r) => r.json(), ), inputSchema: z.object({ location: z.string(), }), outputSchema: z.object({ temperature: z.number(), condition: z.string(), location: z.string(), }), }, ]; ; ``` Docs: [local tools](https://docs.tambo.co/guides/take-actions/register-tools) ### Context, Auth, and Suggestions **Additional context** lets you pass metadata to give the AI better responses. User state, app settings, current page. **User authentication** passes tokens from your auth provider. **Suggestions** generates prompts users can click based on what they're doing. ```tsx ({ key: "selectedItems", value: selectedItems.map((i) => i.name).join(", "), }), currentPage: () => ({ key: "page", value: window.location.pathname }), }} /> ``` ```tsx const { suggestions, accept } = useTamboSuggestions({ maxSuggestions: 3 }); suggestions.map((s) => ( )); ``` Docs: [additional context](https://docs.tambo.co/concepts/additional-context), [user authentication](https://docs.tambo.co/concepts/user-authentication), [suggestions](https://docs.tambo.co/concepts/suggestions) ### Supported LLM Providers OpenAI, Anthropic, Cerebras, Google Gemini, Mistral, and any OpenAI-compatible provider.
