CopilotKit vs kungfu

CopilotKit: CopilotKit is a React framework for embedding AI copilots, chatbots, and in-app agents directly into web applications. It provides UI components (chat interface, sidebar, textarea) and backend infrastructure for building agentic frontends — where AI can read and modify application state, take actions, and render generative UI. Supports LangChain, LangGraph, CrewAI, and custom agent backends.; kungfu: Kungfu keeps a unit of Work outside any single agent session, recording its objective, progress, evidence, next action and completion state, so the same Work can move between Codex, Claude, OpenCode, Amp or your own agent without re-explaining context. Each Agent attempt is recorded under the Work, a second live writer is blocked, and an Agent cannot approve its own result: completion goes through independent review. It is in Alpha.

TL;DR

CopilotKit logo
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.
