CopilotKit

CopilotKit is an enterprise agentic frontend stack for bringing users and AI agents together inside real applications. It is built for creating generative UI apps across web, Slack, and Teams, and it also presents agent interaction in chat apps. The product describes AG-UI as a general-purpose, bi-directional connection between a user-facing application and an agentic backend.

Its feature set includes generative UI, where an agent renders rich, interactive UI across an app, Slack, and Teams as it works. CopilotKit also includes Threads+Persistence, which provides automatic thread and state persistence across app sessions, Slack threads, and Teams conversations. Frontend SDKs are available for React and Angular, and the product also lists chat components as pre-built, customizable UI components. The page says teams can bring their own agents, models, frameworks, or collaboration surfaces, and it mentions first-party integrations from leading agent stacks.

CopilotKit is presented for developers and teams building AI experiences in product apps and messaging surfaces. The site says to start with a single command and an existing app, and it shows use across web, React, Vue, mobile, iOS, Android, Slack, MS Teams, WhatsApp, and Telegram. It also names AG-UI, A2UI, and MCP Apps in its Generative UI Spectrum and includes a section for Slack and Teams integrations.

Pricing is referenced through a pricing page and through feature descriptions that mention premium and intelligence features. The page also includes a GitHub star count and identifies CopilotKit as the company behind the AG-UI protocol.
