Generative UI
Render interactive UI during an agent workflow, including cards, charts, summaries, approvals, and other interface elements that appear inside the app or collaboration surface.
CopilotKit
Freemium
A frontend stack for building agentic apps with generative UI, persistent threads, and flexible deployment.
What is CopilotKit?
CopilotKit is a frontend stack for building agentic applications that bring users and AI agents together inside real products. It centers on the AG-UI protocol, which defines how a user-facing app and an agentic backend stay in sync through a bi-directional event stream.
The product is designed for teams that want agents to act inside the interface rather than in a separate chat window. It supports generative UI, persistent threads, frontend SDKs for React and Angular, and collaboration surfaces such as browser apps, Slack, and Microsoft Teams.
What can CopilotKit do?
AG-UI interaction layer
Connect a user-facing product to an agentic backend through AG-UI so the agent can read state, write state, and stay synchronized with the application.
Threads and persistence
Keep threads and application state durable across app sessions and across supported surfaces such as browser apps, Slack threads, and Teams conversations.
Frontend SDKs
Use pre-built SDKs for React and Angular to add agentic experiences without building the interaction layer from scratch.
Chat components
Start with customizable chat UI components when a chat-based interface fits the workflow, instead of assembling the full experience manually.
Deployment options
Choose hosted, self-hosted, VPC, or on-prem deployment paths from the pricing and platform pages, depending on hosting and control needs.
Use Cases
“Product copilots”
Add an in-app assistant that can answer questions, show stateful UI, and trigger actions while the user stays inside your product.
“Team chat workflows”
Build collaboration workflows in Slack or Microsoft Teams where the agent can render cards, approvals, and threaded follow-ups instead of plain chat replies.
“Persistent app sessions”
Create browser-based agent experiences that keep state across sessions and carry context forward as users return to the app.
“Agent-to-frontend integration”
Connect an existing agent framework or backend to a structured frontend layer so the application UI stays synchronized with agent output.
“Team rollout and deployment”
Use the platform plan that matches your deployment posture, from free developer experimentation to self-hosted or enterprise setups.
Frequently Asked Questions
How do teams get started with CopilotKit?
CopilotKit provides frontend SDKs for React and Angular, and its pricing page also lists agentic backend connections, so teams can connect an existing backend rather than starting from scratch. The home page says you can start with a single command and your existing app.
Is CopilotKit meant only for enterprise teams?
The pricing page shows plans for a single developer seat, small teams, growing teams, and enterprise deployments, including self-hosting and custom terms. That suggests it can be used by individual developers as well as larger teams.
What kinds of outputs can CopilotKit power?
CopilotKit supports generative UI, chat components, shared state and persistence, and AG-UI-based interaction across browser apps, Slack, and Microsoft Teams. The integrations page also notes Slack and Microsoft Teams are in early access, while Discord and Google Chat are planned or coming soon.
Are there any clear limits or caveats?
The source pages describe CopilotKit as a frontend stack and protocol layer for agent-user interaction. They do not present it as a fully turnkey product for every backend or workflow, so teams should expect to integrate it into their own application and agent stack.
How is AG-UI different from MCP or A2A?
The AG-UI page positions AG-UI as the interaction layer between a user-facing application and an agentic backend, while MCP and A2A cover context and agent coordination. CopilotKit builds on AG-UI with clients and platform tooling for production use.
