Most agent frameworks focus on the backend loop. CopilotKit focuses on how the agent appears, asks, updates state, renders results, and asks for confirmation inside a real user interface.
What Sets It Apart
It provides frontend components and protocols for chat UI, generative UI, shared state, and human-in-the-loop workflows. AG-UI helps separate agent logic from React, Angular, mobile, Slack, and other client surfaces.
Who Should Use It
Great fit if agents should feel embedded in an app rather than bolted on as a chat box. Look elsewhere if your agent only needs a simple conversational frontend.
