About Tambo AI
Tambo is an open-source React toolkit for building agents that render UI — also known as generative UI. You register your React components with Zod schemas, and Tambo's agent picks the right component and streams props to it in real time, so users can interact with dynamic, AI-driven interfaces. It ships with a hosted backend (Tambo Cloud) or a self-hostable option via Docker, and supports MCP, multiple LLM providers, and persistent stateful components out of the box.
- Generative Components — Register components with Zod schemas; the agent selects and streams props to render charts, summaries, and data visualizations automatically.
- Interactable Components — Use
withInteractableto create persistent, updatable components like task boards, shopping carts, and spreadsheets that respond to user refinements. - Streaming Infrastructure — Props stream to components as the LLM generates them; cancellation, error recovery, and reconnection are handled automatically.
- MCP Integration — Connect to Linear, Slack, databases, or custom MCP servers using the full MCP protocol including tools, prompts, elicitations, and sampling.
- Local Tools — Define browser-side functions (DOM manipulation, authenticated fetches, React state access) that the AI can call as tools.
- Multi-Provider LLM Support — Works with OpenAI, Anthropic, Google Gemini, Mistral, Cerebras, and any OpenAI-compatible provider.
- Tambo Cloud or Self-Host — Cloud is a hosted backend free to start with credits; self-hosted runs the same backend on your own infrastructure via Docker.
- Context, Auth & Suggestions — Pass user state, app settings, and OAuth tokens as context; generate clickable prompt suggestions based on what users are doing.
- Pre-built Component Library — Access agent and generative UI primitives at ui.tambo.co, plus starter templates for chat interfaces and analytics dashboards.
- Get Started in 5 Minutes — Run
npm create tambo-app my-tambo-app, wrap your app withTamboProvider, register components, and start building.
