Summary

OpenUI 1.0 brings ChatGPT-style generative UI to any app or agent, working with both closed and open models by converting an app's component library into a system prompt and rendering LLM output in the product's own design system.

This is a good news for front-end engineers. ChatGPT has generative UI built in, and OpenUI 1.0 brings it to every other app and agent. It also works with any model, closed or open, including ones running on your own hardware, so the UI layer isn’t tied to a single provider. The developer picks the components, the model picks what the answer needs, OpenUI renders it in the product’s own design. The developer registers the app’s own UI components (hotel cards, maps, charts, booking forms) with OpenUI, which converts that component library into a system prompt telling the LLM exactly what it may use. When a user asks something, the LLM, whether GPT, Claude or a self-hosted open model, replies in OpenUI Lang, a compact markup that names the components the answer needs and fills them with data, instead of writing prose. OpenUI’s renderer reads that markup as it streams, checks it against the registered components, and draws the screen with the app’s real components, so the answer arrives as working interface in the app’s own design system.

Rabi Shanker Guha (@rabi_guha): For 30 years, technology has moved in one direction: turning information into intuitive interfaces

Somehow, the smartest software we’ve ever built took us back to a textbox

We’ve spent the last 2 years at @openuidev trying to fix that. 6 months ago we open-sourced it: 10K+
