CopilotKit vs Fray
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.; Fray: Fray is an open-source WAF security testing toolkit designed to provide a complete workflow for security professionals, from automated crawling and parameter discovery to payload injection and reporting. Unlike static payload collections, Fray offers a dynamic approach to scanning, detecting WAFs, and testing against 5,500+ payloads across 24 OWASP categories.
