Churnkey SDK

A production-ready cancel flow for React. Open source. Optionally connects to Churnkey for analytics and AI-powered retention.

Packages

PackageDescription
@churnkey/reactThe cancel flow. Drop-in component, headless hook, or core state machine. React 18 and 19.
@churnkey/nodeServer-side token generation. Only needed if Churnkey is handling billing actions for you, or if you're using the hosted embed.
@churnkey/mcpModel Context Protocol server. Lets Claude, Cursor, and other AI agents query your Churnkey data (sessions, analytics, DSR) using a Data API key.

Quick start

npm install @churnkey/react
import { CancelFlow } from '@churnkey/react'
import '@churnkey/react/styles.css'

<CancelFlow
  steps={[
    {
      type: 'survey',
      title: 'Why are you leaving?',
      reasons: [
        {
          id: 'expensive',
          label: 'Too expensive',
          offer: { type: 'discount', couponId: 'STRIPE_SAVE20', percentOff: 20, durationInMonths: 3 },

      ],
    },
    { type: 'feedback', title: 'Anything else?' },
