OpenUI is a full-stack, renderer-agnostic Generative UI framework built around OpenUI Lang, a compact streaming-first language that lets AI models generate structured UI with up to 67% fewer tokens than JSON.
Morphic is an AI-powered search engine with a generative UI that renders rich inline components from streamed JSON specs, supporting multiple AI and search providers, chat history, auth, and Docker deployment.
Better Design is an open-source MCP server and shadcn/ui registry that supplies AI coding agents with design systems, semantic CSS tokens, component overrides, UI principles, icon matching, and WCAG-oriented review rules. It includes 31 themes and connects to Claude Code, Cursor, VS Code/GitHub Copilot, Claude Desktop, and other MCP clients.
CopilotKit is an SDK for building agent-native apps with Generative UI, shared state, and human-in-the-loop workflows on React, Angular, Vue, React Native, Slack, and Microsoft Teams. MIT-licensed; the team behind the AG-UI Protocol.
