Tambo Cloud is shutting down. New signups are closed. Tambo Cloud keeps running until October 31, 2026, after which the hosted API stops responding; user data is deleted November 30, 2026. Read the announcement. Tambo is open source and self-hostable: see SELF-HOSTING.md to keep running it yourself. The team is now building Charming, a collaborative cloud for apps built with any AI agent.
The open-source generative UI toolkit for React. Connect your components—Tambo handles streaming, state management, and MCP.
Shutdown Notice • Self-Host • Docs • Discord
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 <Chart>. "Add a task" updates your <TaskBoard>.

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.
npm create tambo-app my-tambo-app # auto-initializes git + tambo setup
cd my-tambo-app
npm run devTambo Cloud is the hosted backend; new signups are closed and it shuts down October 31, 2026 (announcement). Self-hosted runs on your own infrastructure; see SELF-HOSTING.md.
Check out the pre-built component library for agent and generative UI primitives:

Or fork a template:
| Template | Description |
|---|---|
| AI Chat with Generative UI | Chat interface with dynamic component generation |
| AI Analytics Dashboard | Analytics dashboard with AI-powered visualization |
Tell the AI which components it can use. Zod schemas define the props. These schemas become LLM tool definitions—the agent calls them like functions and Tambo renders the result.
Render once in response to a message. Charts, summaries, data visualizations.

Wrap your app with TamboProvider. You must provide either userKey or userToken to identify the thread owner.
<TamboProvider
apiKey={process.env.NEXT_PUBLIC_TAMBO_API_KEY!}
userKey={currentUserId}
components={components}
>
<Chat />
<InteractableNote id="note-1" title="My Note" content="Start writing..." />
</TamboProvider>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 for details.
Docs: provider options
useTambo() is the primary hook — it gives you messages, streaming state, and thread management. useTamboThreadInput() handles user input and message submission.
const { messages, isStreaming } = useTambo();
const { value, setValue, submit, isPending } = useTamboThreadInput();Docs: threads and messages, streaming status, full tutorial
Connect to Linear, Slack, databases, or your own MCP servers. Tambo supports the full MCP protocol: tools, prompts, elicitations, and sampling.
import { MCPTransport } from "@tambo-ai/react/mcp";
const mcpServers = [
{
name: "filesystem",
url: "http://localhost:8261/mcp",
transport: MCPTransport.HTTP,
},
];
<TamboProvider
apiKey={process.env.NEXT_PUBLIC_TAMBO_API_KEY!}
userKey={currentUserId}
components={components}
mcpServers={mcpServers}

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.
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(),
}),
},
];
<TamboProvider
apiKey={process.env.NEXT_PUBLIC_TAMBO_API_KEY!}
userKey={currentUserId}
tools={tools}
components={components}
>
<App />
</TamboProvider>;Docs: local tools
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.
<TamboProvider
apiKey={process.env.NEXT_PUBLIC_TAMBO_API_KEY!}
userToken={userToken}
contextHelpers={{
selectedItems: () => ({
key: "selectedItems",
value: selectedItems.map((i) => i.name).join(", "),
}),
currentPage: () => ({ key: "page", value: window.location.pathname }),
}}
/>const { suggestions, accept } = useTamboSuggestions({ maxSuggestions: 3 });
suggestions.map((s) => (
<button key={s.id} onClick={() => accept(s)}>
{s.title}
</button>
