Widgets

Widgets is an open-source generative UI kit that enables language models to write compact, JSX-like templates which are then rendered into polished, interactive components. The system validates both the model output and supplied data before rendering, ensuring no arbitrary code execution. It includes 144 registered components, 200+ icons, and full light/dark theming support.

Designed for developers building AI chat interfaces and agent applications, Widgets provides a registry of pre-built components including containers, forms, charts, media players, and agent-native primitives like approval cards and streaming text displays. The project describes itself as an open-source alternative to OpenAI ChatKit widgets. Built with React, Tailwind, and shadcn/ui, it offers a playground for live template editing and AI-powered widget generation.
