We are the company behind the **AG-UI Protocol**, adopted by Google, LangChain, AWS, Microsoft, Mastra, PydanticAI, and more! https://github.com/user-attachments/assets/de5bcc17-1b51-4092-9a85-42971ecc1f4c **Features:** - **Chat UI** – A React-based chat interface that supports message streaming, tool calls, and agent responses. - **Backend Tool Rendering** – Enables agents to call backend tools that return UI components rendered directly in the client. - **Generative UI** – Allows agents to generate and update UI components dynamically at runtime based on user intent and agent state. - **Shared State** – A synchronized state layer that both agents and UI components can read from and write to in real time. - **Human-in-the-Loop** – Lets agents pause execution to request user input, confirmation, or edits before continuing. https://github.com/user-attachments/assets/55bf6714-62a7-4d5d-9232-07747cc0763b ## Quick Start ### New projects: ```bash npx copilotkit@latest create -f <framework> ``` ### Existing projects: ```bash npx copilotkit@latest init ``` https://github.com/user-attachments/assets/7372b27b-8def-40fb-a11d-1f6585f556ad What this gives you: - **CopilotKit installed** – Core packages are fully set up in your app - **Provider configured** – Context, state, and hooks ready to use - **Agent <> UI connected** – Agents can stream actions and render UI immediately - **Deployment-ready** – Your app is ready to deploy [Complete getting started guide →](https://docs.copilotkit.ai/langgraph/quickstart) ## How it works: CopilotKit connects your UI, agents, and tools into a single interaction loop.  This enables: - Agents that ask users for input - Tools that render UI - Stateful workflows across steps and sessions ## ⭐️ useAgent Hook The `useAgent` hook is a proper superset of `useCoAgent` and sits directly on AG-UI, giving more control over the agent connection. ```ts // Programmatically access and control your agents const { agent } = useAgent({ agentId: "my_agent" }); // Render and update your agent's state return <div> <h1>{agent.state.city}</h1> <button onClick={() => agent.setState({ city: "NYC" })}> Set City </button> </div> ``` Check out the [useAgent docs](https://go.copilotkit.ai/useagent-docs) to learn more. https://github.com/user-attachments/assets/67928406-8abc-49a1-a851-98018b52174f ## Generative UI Generative UI is a core CopilotKit pattern that allows agents to dynamically render UI as part of their workflow. https://github.com/user-attachments/assets/3cfacac0-4ffd-457a-96f9-d7951e4ab7b6 ### Compare the Three Types <img width="708" height="311" alt="image" src="https://github.com/user-attachments/assets/962f49c2-31ea-43c5-b2a3-7cdde114705a" /> #### Explore: - [Static (AG-UI Protocol)](https://docs.copilotkit.ai/ag-ui-protocol) - [Declarative (A2UI)](https://docs.copilotkit.ai/generative-ui/specs/a2ui#using-a2ui-with-copilotkit) - [Open-Ended (MCP Apps & Open JSON)](https://docs.copilotkit.ai/generative-ui/specs/mcp-apps) [Generative UI educational repo →](https://github.com/CopilotKit/CopilotKit/tree/main/examples/showcases/generative-ui) ## 🖥️ AG-UI: The Agent–User Interaction Protocol Connect agent workflow to user-facing apps, with deep partnerships and 1st-party integrations across the agentic stack—including LangGraph, CrewAI, and more.
