CopilotKit
Basic Information
CopilotKit is an open source developer toolkit and UI library for building and deploying in-app AI assistants, chatbots, and agent workflows. The repository provides a CLI to bootstrap projects, headless APIs for full control over agent state and messaging, and pre-built customizable React components for embedding assistants into web apps. It is framework-agnostic with explicit support for React, Next.js and integrations with agentic tooling such as LangGraph and the AG-UI protocol. The README highlights production-ready features like streaming support, human-in-the-loop approval patterns, and built-in prompt-injection protections. CopilotKit also links to cloud services, documentation, examples (form-filling, state machines, chat-with-your-data), and community channels to help teams integrate agentic capabilities into their applications quickly and securely.
