The frontend stack for AI agents and generative UI in React, Angular, mobile and chat apps
Decide what you want to achieve with CopilotKit and check the README on GitHub for requirements before installing.
Clone the repository from GitHub (or take the packaged install route in step 3 if the README offers one).
Follow the project's documented install commands — the Run section below lists the exact ones — and add any required API keys or models.
Work through the README's quickstart example end to end, then adapt it to your own project or data.
Agents render rich, app-native UI components — not just text — so results appear as cards, forms and dashboards inside your product.
A first-class hook (highlighted in the README as the useAgent hook) connects your frontend components to a running agent's state and actions.
Built on AG-UI, the open Agent-User Interaction protocol from the same team, so any AG-UI-compatible agent backend can drive the UI.
The same agent can surface in web and mobile apps and in chat channels such as Slack, per the project's channel support.
Designed to plug into existing React, Angular, Next.js and mobile codebases rather than forcing a rewrite.
Official skills and CLI scaffolding (copilotkit create / create-ag-ui-app) help you start a new agent app or add CopilotKit to an existing one.

git clone https://github.com/CopilotKit/CopilotKit.git
cd CopilotKitUse the official scaffolding CLI to generate a ready-to-run agent application.
npx copilotkit@latest createRun the onboarding command in your existing app, or scaffold a plain AG-UI app with create-ag-ui-app.
npx --yes copilotkit@latest onboard start
# alternative: npx create-ag-ui-app my-agent-appCopilotKit is maintained by the CopilotKit organization/account on GitHub, together with open-source contributors, in the public repository CopilotKit/CopilotKit.
Yes — the code is open source under the MIT license. You can use, modify and redistribute it under that license's terms.
CopilotKit itself is free and open source, but the agent you connect it to usually needs an LLM — so in practice you bring your own model provider API key (or a self-hosted agent backend).
Unlike a plain chat widget, CopilotKit is built around the AG-UI protocol and generative UI, so agents can render and control real app components, not only stream text.
Clone the repository from GitHub, follow the install commands in the Run section (taken from the project's README), and complete the documented quickstart example before adapting it to your own use case.

Vercel's AI SDK: the TypeScript toolkit for building AI apps and agents with any model provider
Open, event-based protocol that connects AI agents to user-facing apps with streaming and shared state.
A lightweight, cross-platform code editor, built with Tauri (Rust and React) with Git support, AI agents, vim keybindings
One Rust CLI for every LLM: shell assistant, chat REPL, RAG, tools and agents across 20+ providers.
Reverse engineer anything with agents - from app behavior down to native binaries
