CopilotKit vs wassette
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.; wassette: Wassette is a security-oriented runtime that executes WebAssembly Components via MCP, making it easy to extend AI agents with new tools directly from a chat window. It leverages the Wasmtime security sandbox to provide browser-grade isolation, ensuring that these reusable components run safely.
