Churnkey SDK

Hi, this is a really big decision for us. We spent the last 5 years refining and selling our cancel flows product suite. Our entire team uses Claude Code. So, we understand that with LLMs, a competent engineer can stand up a “good enough” version of our cancel flow product in days. And if people are going to build one, we'd rather give them one that has saved over 2 million customers and get their weekend back. What can't be vibe-coded in an afternoon is what we are here to sell.

Churnkey SDK launched on June 2, 2026 with 13 votes, #1,084 of 22,647 launches that month and more than 90% of that year's launches.

What it does

An open-source cancel flow for React. Survey, offers, feedback, and confirmation in one component. Optionally connects to Churnkey for analytics, A/B testing, and AI retention features.

Drop-in React cancel flow. Free out of the box. Connect Churnkey for analytics, A/B testing, and the No-Code Editor. Add the Intelligence tier for Adaptive Offers, Feedback AI, and Automatic AI Translations.

Survey, offers, feedback, and confirmation in one component. Optionally connects to Churnkey for analytics, A/B testing, and AI retention features. import { CancelFlow } from '@churnkey/react' import '@churnkey/react/styles.css' <CancelFlow steps={[ { type: 'survey', reasons: [ { id: 'expensive', label: 'Too expensive', offer: { type: 'discount', couponId: 'SAVE20', percentOff: 20 }, }, { id: 'not-using', label: "Not using it" }, ], }, { type: 'feedback' }, { type: 'confirm' }, ]} handleDiscount={async (o) => myBilling.applyCoupon(o.couponId)} handleCancel={async () => myBilling.cancel()} /> Copy How it grows Three integration levels, one component.

    I originally built this app to organize and reuse interesting React + Tailwind components I came across on Twitter, inspired by the shadcn&#x2F;ui approach. Later, a friend started contributing their own components, and it got me thinking—this could grow into something bigger, like an NPM for design engineers to share and use components. Would love to hear your thoughts!

    If you’ve ever tried building onboarding or product adoption with Appcues, Chameleon, Userflow, WalkMe, or Usetiful, you’ve probably hit the same two problems: 1. Everything is rendered with JavaScript overlays 2. Customization is a nightmare A little backstory: When I was choosing an onboarding tool for my previous project, nothing matched what I needed. So I had to build my own. With help from IntroJS I built onboarding solution that I needed: Tooltips, Modals, custom CSS, waiting for interactions, and saving the state into the database. It worked… but it took way more time than it should…

    Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

Happy to discuss any questions here!
