buoy vs CopilotKit

buoy: Buoy is an in-app developer toolkit that provides a floating menu to inspect and modify the state of a running application. It allows developers to check web calls, storage, query caches, routes, renders, and performance, facilitating on-the-fly debugging and environment manipulation.; 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.

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.
