Tambo 1.0: Open-source toolkit for agents that render React components

#1

Post by grouchy »

Hi HN — cofounder Michael here.

We've been building Tambo for about a year, and just released our 1.0.

We make are making it easier to register React components with Zod schemas, a build an agent picks the right one and renders the right props.

We handle many of the complications with building generative user interfaces like: managing state between the user, the agent, and react component, rendering partial props, and we handle auth between your user, and MCP. We also support adding MCP servers and most of the spec.

We are 100% open-source and currently have 8k+ GitHub stars, thousands of developers, and over half-millions messages processed by our hosted service.

If you're building AI agents with generative UI, we'd like to hear from you.

Is there any interest or discussion about finding a way to use these tools to work with MCP Apps?

Since I didn't see it in the Readme, how does this compare to something like Google's A2UI? Seems like it's doing more, but could e.g. Tambo work on top of A2UI protocol or is it a different beast?

My agents need a UI and I'm in the market for a good framework to land on, but as is always the case in these kinds of interfaces I strongly suspect there will be a standard inter-compatible protocol underlying it that can connect many kinds of agents to many kinds of frontends. What is your take on that?

There’s an MCP Apps version of this that is interesting: https://creature.run

Maybe I’m misunderstanding, but isn’t generating UI just-in-time kind of risky because AI can get it wrong? Whereas you can generate/build an MCP App once that is deterministic, always returns a working result, and just as AI native.

congrats on the launch! we're building type.com and we would love to use this - shoot me an email: k at type dot com

our use case is to allow other users to build lightweight internal apps within your chat workspace (say like an applicant tracking system per hire etc.)

With this you build your own React components and register them with the AI. The AI chooses which to use and what props to pass into them, so it's not generating UI from scratch, if that's what you mean - other Michael from the Tambo team
