Introduction

Hi HN — cofounder Michael here. We’ve been building Tambo for about a year, and just released our 1.0.

What Tambo Does

We make it easier to register React components with Zod schemas, so an agent can pick the right one and render the right props. Tambo handles many complications of building generative user interfaces, including:

  • Managing state between the user, the agent, and the React component
  • Rendering partial props
  • Handling authentication between your user and MCP
  • Supporting addition of MCP servers and most of the spec

Open Source & Adoption

Tambo is 100 % open‑source and currently has 8k+ GitHub stars, thousands of developers, and over half a million messages processed by our hosted service.

Get In Touch

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