Chatbots can now stream generative UI with JSON-render

Vercel released json-render, a tool that lets Chat SDK agents stream generative UI by writing a JSON spec against a typed component catalog, which json-render converts into a Chat SDK card. Each adapter posts the card in its platform's native format, such as Block Kit on Slack and Adaptive Cards on Teams, and the catalog covers tables, charts, buttons and more, removing the need for a separate tool per message shape.

In case you missed it!

You can now stream generative UI from your Chat SDK agent with json-render.

With a typed catalog of components, the agent writes a JSON spec that json-render converts into a Chat SDK card. Each adapter then posts the card in its platform’s native format, such as Block Kit on Slack and Adaptive Cards on Teams.

The catalog covers tables, charts, buttons, and more, so there’s no separate tool to build and maintain for each message shape.
