If you’ve been building anything with LLMs in React, you’ve probably hit the same wall I did — the AI spits out a block of text, and then you’re stuck figuring out how to turn that into something your users can actually interact with. That’s exactly the problem [Tambo](https://tambo.co/) solves, and honestly, it’s one of those “why didn’t this exist sooner” moments.

Tambo is an open-source generative UI toolkit for React. The idea is simple: you register your components with Zod schemas, and when a user sends a message, the AI agent figures out which component to render and streams the props directly into it. Say a user types “show me sales by region” — instead of getting a paragraph of text, they get your actual Chart component, fully populated with data. Someone asks to “add a task,” and your TaskBoard updates live. No custom routing logic, no giant switch statements mapping intents to views.

I first noticed it when it started climbing [GitHub’s daily trending](https://github.com/tambo-ai/tambo) around February 13th, and it’s been sitting there for days now with over 9,600 stars. The [Hacker News thread](https://news.ycombinator.com/item?id=46966182) had some solid discussion too, with developers digging into the architecture and comparing it to what Vercel’s AI SDK offers.

What makes Tambo practical rather than just cool is the production readiness. It supports two component patterns — generative components that render once (think data visualizations and summaries) and interactable components that persist and update as users refine their requests (shopping carts, spreadsheets, that sort of thing). Props stream in as the LLM generates them, and the SDK handles cancellation, error recovery, and reconnection under the hood. You can bring your own API key from OpenAI, Anthropic, Gemini, Mistral, or any OpenAI-compatible provider. It’s also SOC 2 and HIPAA compliant, which matters if you’re shipping this in a real product.

The adoption numbers speak for themselves — teams at Zapier, Rocket Money, and Solink are already using it in production, with over 500,000 user messages processed. You can check it out on [Product Hunt](https://www.producthunt.com/products/tambo) or dive straight into the [docs](https://docs.tambo.co/). If you’re tired of writing glue code between your LLM and your UI, Tambo is worth a serious look.
