CopilotKitDev Tooling · ★ 38.2k

When to choose:

You are building a React, Angular, Vue, or React Native app and need an MIT-licensed frontend layer for in-app AI copilots, generative UI, and human-in-the-loop state sharing.
You want to connect your existing LangGraph, CrewAI, or custom agent backend to web apps, Slack, and Microsoft Teams via the AG-UI protocol.

When to skip:

You are looking for a backend agent orchestration engine rather than a frontend/UI integration SDK; use CrewAI, Pydantic AI, or LangGraph for the backend.
You want a standalone desktop chat client for personal use; use Cherry Studio.
