# CopilotKit

**CopilotKit** is an open-source framework and company developing agent-user interaction infrastructure, generative UI primitives, and the [AG UI (Agent User Interaction) protocol](/wiki/ag-ui-protocol). [[source: ag-ui-protocol-specification-2026]](/wiki/raw/articles/ag-ui-protocol-specification-2026)

## Core Initiatives & Contributions

### 1. The AG-UI Protocol
CopilotKit originated the AG-UI specification in partnership with LangChain, CrewAI, and ecosystem partners, establishing a standard event stream protocol (SSE/WebSocket) between backend agent runtimes and frontend client applications. [[source: ag-ui-protocol-specification-2026]](/wiki/raw/articles/ag-ui-protocol-specification-2026)

### 2. Generative UI and Client Tooling
CopilotKit provides client runtime adapters across React, React Native, Next.js, and Angular, alongside multi-surface transports such as the Channels SDK for Slack and Microsoft Teams. [[source: copilotkit-cma-agui-2026]](/wiki/raw/articles/copilotkit-cma-agui-2026)

### 3. Claude Managed Agents Integration
In August 2026, CopilotKit collaborated with [anthropic](/wiki/anthropic) to release first-class AG-UI adapters for [claude managed agents](/wiki/claude-managed-agents), standardizing Anthropic's hosted event logs into client-rendered generative UI and interactive human-in-the-loop approval gates.
