CopilotKit and OpenGenerativeUI
OpenGenerativeUI is an earlier-stage, open-source research framework that CopilotKit evolved from or was inspired by, with CopilotKit now being the mature, production-ready successor offering the AG-UI Protocol and broader framework support (React + Angular).
About CopilotKit
CopilotKit/CopilotKit
The Frontend Stack for Agents & Generative UI. React + Angular. Makers of the AG-UI Protocol
Provides backend tool rendering and dynamic generative UI where agents stream actions that materialize UI components directly in the client, plus a synchronized state layer enabling real-time bidirectional updates between agents and frontend. Built on the AG-UI Protocol standard, it integrates with LangGraph, CrewAI, and other agentic frameworks, with the `useAgent` hook giving programmatic control over agent state and execution from React components.
About OpenGenerativeUI
CopilotKit/OpenGenerativeUI
Open-Source Generative UI Framework
Combines CopilotKit with LangChain Deep Agents to generate interactive visualizations—algorithm animations, 3D scenes, charts, and diagrams—rendered in sandboxed iframes with automatic theming and progressive loading. Uses a skills-based architecture where visualization instructions are defined as modular `SKILL.md` files and loaded on-demand by the agent, rather than baked into the system prompt. Exposes a Model Context Protocol server that wraps HTML fragments with design system CSS and provides skill resources to MCP-compatible clients like Claude Desktop and Cursor.
