Bring your AWS Strands agents
into any app
CopilotKit is an open-source framework that connects your app to AWS Strands agents. Give your agents chat, generative UI, human-in-the-loop, rich threads, automatic learning and more.
Strands and CopilotKit running together, in the React frontend. Every demo below is the same integration with one capability turned on.
Build with AWS Strands
Strands gives you the agent: a model, a tool loop and the state it carries between turns. What it does not give you is the surface. Somewhere for the conversation to happen, a way to show the run while it is running, and a moment for a person to step in. Each capability below builds on something your agent already does.
Generative UI
Your agent calls tools and reports progress as it works. CopilotKit streams that to the browser and renders each step as a an Angular component, instead of leaving the user with a spinner.
Read the docs Live demoHuman-in-the-loop
A frontend tool registered with useHumanInTheLoop renders your own UI, waits for the user's answer, and hands it back to the agent as the tool result.
Read the docs Live demoShared state
Your agent keeps state on the server between turns. CopilotKit mirrors it into your app and back, so a user edit and an agent write land in the same place.

Connect your agent
Your agent keeps running as its own Python service, with the AG-UI bridge from ag_ui_strands in front of it. CopilotKit reaches that service over HTTP, so nothing inside the agent changes.
import {
CopilotRuntime,
createCopilotRuntimeHandler,
} from "@copilotkit/runtime/v2";
import { HttpAgent } from "@ag-ui/client";
const runtime = new CopilotRuntime({
agents: {
my_agent: new HttpAgent({ url: process.env.AGENT_URL! }),
},
});
const handler = createCopilotRuntimeHandler({
runtime,
basePath: "/api/copilotkit",
});
export const GET = handler;
export const POST = handler;
