CopilotKit

Frontend SDK for integrating AI agents into applications with real-time context, UI control, and automatic learning.

Overview

CopilotKit is an enterprise-ready frontend stack for building AI agents directly into applications. It provides a bi-directional connection (AG-UI protocol) between user-facing apps and agentic backends, enabling agents to render rich interactive UI, take actions through APIs, and learn from real user interactions.

The platform supports multiple frameworks (React, Vue, Angular, iOS, Android) and integrates with major LLM providers and agent frameworks. Key capabilities include generative UI rendering, automatic learning loops that improve agent quality over time, comprehensive audit trails, and product analytics specifically designed for agentic applications.

CopilotKit can be self-hosted for full data control or deployed via their managed Copilot Cloud, making it suitable for organizations from early prototypes through enterprise-scale production deployments.
